If the equilibrium concentration found in the reaction. 2A(g) + B(g) rightarrow

Question

If the equilibrium concentration found in the reaction. 2A(g) + B(g) rightarrow 2C(g) Are [A] = 0 30 M, [B] = 0.10 M. and [C] = 0.20 M, calculate the value of K_c. 0 23 4.4 6.7 3.3 Which statement below is TRUE? The rate of the forward reaction is greater than the rate of the reverse reaction at equilibrium. The rate of the forward reaction is slow at first, then increases to a maximum at equilibrium. The rate of the forward reaction is equal to the rate of the reverse reaction a equilibrium. Equilibrium and kinetics cannot be compared.

Explanation / Answer

9.

K = [C]^2 /[A]^2 [B]

K = (0.2^2) / ((0.3^2)(0.1))

K = 4.4444

10.

in equilibrium; the rate forward = rate backwards/reverse, choose C
