For a vapour phase catalytic reaction (A + B → P) which follows the Ridel mechanism and the reaction step is rate controlling, the rate of reaction is given by (reaction rate is irreversible, product also absorbs)?
A-rA = (k. PA. PB)/(1 + KAPB + KBPB. KPPP)
B-rA = (k. PA. PB)/(1 + KAPA)
C-rA = (k. PA
D-rA = (k. PA. PB)/(1 + KAPA + KPPP)
Correct answer
D. -rA = (k. PA. PB)/(1 + KAPA + KPPP)
Explanation
The correct answer is -rA = (k. PA. PB)/(1 + KAPA + KPPP).
