(a) K2K33/K1 like share and subscribe the channel https://www.youtube.com/channel/UCWSwCHgqRoxwP3eOPBWn9NA. for any doubt : vijendersolanki69@gmail.co.. Yes, but I think we need to define the variable k before using it (or state that k = K1K2k3) Also note that K1 and K2 are equilibrium constants (capitalized K). We can also write it in terms of the rate constant since K = (k/k'), with k being rate constant for the forward rxn and k' being rate constant for reverse reaction. So k = K1 K2 k3 p = oxygen pressure and K1, K2, K3 and K4 are the respective equilibrium constants of the reactions Hb4 + 02Hb402, Hb402 + 02= Hb,04, Hb404 + 02= Hb , Hb06 + 02Hb408. Until recently there has been no decisive method of testing this equation quantitatively or of determining the values of the intermediate constants K K2, K3 and K4 The third equation is the sum of the first two. In this case, it can be shown that if the third equation is the sum of the other two equations, then K3 is the product of K1 and K2. This is true in general for any set of equations. So K3 = (2 x 10^105) • (7 x 10^24) = 1.4 x 10^13

k3 = k1.k2 k3 = (k1.k2)0.5 k3(k1+k2)/2 k3 = (k1.k2)2 Answer & Explanation MCQs 1: For a vapour phase catalytic reaction (A + B → P) which follows the Ridel mechanism and the reaction step is rate controlling, the rate of reaction is given by (reaction rate is irreversible, product also absorbs) Thus the product of the equilibrium constant expressions for K1 and K2 is the same as the equilibrium constant expression for K3: K3 = K1K2 = (2.0 × 10 − 25)(6.4 × 109) = 1.3 × 10 − 15.

F1=-k1(x1)+k2(x2-x1) F2=-k2(x2-x1)-k3(x2) I looked around the internet and believe these equations are correct, however, my problem is converting them to work with the initial values in the problem. At equilibrium, the force on block 1 is 0 and x1 is 0. Using this I got the equation F1=-x1(k1+k2 An equilibrium is established in which both the forward (fwd) and the reverse (rev) reactions are elementary. If the equilibrium constant Kc = 1.6 × 10-2 and the rate constant kfwd = 8.0 × 10-7 s-1 what is the value of krev Equilibrium is when the rate of the forward reaction equals the rate of the reverse reaction. All reactant and product concentrations are constant at equilibrium. Given a reaction , the equilibrium constant , also called or , is defined as follows: For reactions that are not at equilibrium, we can write a similar expression called the reaction.
The equilibrium constants do not include the concentrations of single components such as liquids and solid and they may have units depending on the nature of the reaction (although thermodynamic equilibrium constants do not). Here are some easy steps on writing gas equilibrium constants (this is the same for finding K c, K p, K sp, Q and etc.): The only difference between the Km and Kd expressions is the presence of kcat in Km's numerator. Thus, whether Km is equal to Kd depends only on the relative size of k-1 and kcat. They are equal when k-1 is much larger than kcat. This condition provides a more precise way of thinking about when the rapid equilibrium assumption is valid: when. The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change.For a given set of reaction conditions, the equilibrium constant is independent of the initial analytical concentrations of the.

I'm assuming that when you say series, the springs are attached to each other, forming a long chain. First off, for this type of question, you need to remember the fact that the force from a spring comes from how long it is stretched multiplied by.. equilibrium constant is related to the energy of converting HGH into G+2H and the energy for this conversion is a state function (it is independent of the path) then product of k2 and k4 which link the same beginning and end points must equal the product of k1 and k3. Now we have three equations and four unknowns. So to relate the macroscopic. This system of two parallel springs is equivalent to a single Hookean spring, of spring constant k. The value of k can be found from the formula that applies to capacitors connected in parallel in an electrical circuit. k = k1 + k2. Series. When same springs are connected as shown in the figure below, these are said to be connected in series
