Two gaseous compounds, A and B are introduced into an evacuated reaction chamber. The resulting reaction is exothermic and the balanced chemical equation is shown below.
A(g) + B(g) ---> C(g)
As A and B are initially introduced into the reaction chamber, which statement about the rates of the reaction is true?
(A) The rates of the forward and reverse reaction are the same.
(B) The rate of the forward reaction is faster than the rate of the reverse reaction.
(C) The rate of the forward reaction is slower than the rate of the reverse reaction.
(D) The rate cannot be determined without knowing the rate laws.
