Answer to Question #118739 in General Chemistry for Amanda

Question

Methane reacts with steam over a nickel powder catalyst. The reaction equation is: CH4(g)+2H2O(g)+heat=CO2(g)+4H2(g)
Use this information to answer:
We can predict that, every reagent in the equation will have increased, except
A. Methane
B. water
C. carbon dioxide
D. hydrogen
When this gaseous reaction system at equilibrium is disturbed by heating the autoclave, we theorize that
A. both forward and reverse reaction rates increase, but the forward rate increases more
B. the forward reaction rate does not change, but the reverse reaction rate increases
C. the reverse reaction rate does not change, but the forward reaction rate increases
D. both reaction rates increase equally, so the equilibrium position is unchanged
A test reaction is done starting with only methane and excess water in the autoclave. Initial concentration of methane is 0.112 mol/L, and 0.017 mol / L at equilibrium, the equilibrium concentration of hydrogen is __ mol/L.
