Consider the Following Reaction Occurring at 960 K: CO₂(g)

question 91

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
