Question

Consider the following system with the following concentrations:

:

CO(g)+H2O(g)⇌CO2(g)+H2 K= 1.0

[CO2]= 0.2 M

[H2]=2.0M

[CO]=1.0M

[H2O]=1.0M

Which of the following is true about this system?

a)This reaction is at equilibrium

b)This reaction will shift left

c)This reaction will shift right

d)There is not enough information given

Answer 1

Q = [CO2][H2] / [CO][H2O] = (0.2)(2.0) / (1.0)(1.0) = 0.4

K = 1.0

Since Q < K, the system is not at equilibrium and lies more toward the reactant side. Thus, the answer would be (C) the reaction will shift right
