Question

Given the equation A(g)  B(g) + 2C(g). At a particular temperature, K =  . If you mixed 1.4 mol B, 0.050 mol C, and 0.0050 mol A in a 1-liter container, in which direction would the reaction initially proceed?

Quizplus · Accepted Answer

We can calculate the reaction quotient Qc:
Qc = ([B]^11/2[C]^2)/[A] = [(1.4)^11/2(0.050)^2]/(0.0050) = 11,200
Since Qc < K, the reaction is not yet at equilibrium and will proceed to the right to reach equilibrium. Therefore, the answer is A.
