Consider the Following Reaction Occurring at 960 K

question 19

Multiple Choice

Consider the following reaction occurring at 960 K:
CO₂(g) + H₂(g) ⇌ CO(g) + H₂O(g)
At equilibrium,the concentrations of reactants and products are: [CO₂] = 0.0400 M,[H₂] = 0.0220 M,[CO] = 0.0240 M,and [H₂O] = 0.0190 M.This equilibrium is perturbed by adding CO₂(g) to the system such that when a new equilibrium is reached,the concentration of CO₂ is 0.050 M.What is the concentration of H₂(g) at this equilibrium?

• A)0.050 M
• B)0.482 M
• C)0.462 M
• D)0.300 M
• E)0.0504 M
