Question

Conisder the following elementary reaction,
`2A + B + C rarr` Products. All reactants are present in the gaseous state and reactant `C` is taken in excess.
What is the rate expresison of the reaction?
A. Rate `= k[A]^(2)[B][C]`
B. Rate `= k[A]^(2)[B]`
C. Rate `= k([A]^(2)[B])/([C])`
D. Rate `= k[C]^(0)`

Answer 1

Correct Answer - B
Since `C` is taken in excess, so its concentration does not change. So it not taken in rate expresison of the reaction.
