The rate equation for the reaction represented by as shown in the bellow figure, is given by - rx = K1 . Cx/(1 + K2 Cx). At high value of Cx (i.e.., K2Cx > > 1), the order of the reaction and the rate constant are respectively___________________?
Correct answer: A. Zero order & K1/K2
- A. Zero order & K1/K2
- B. Zero order & K1
- C. First order & K1
- D. First order & K1/K2
Explanation
When K2Cx is much greater than one, the denominator is approximately K2Cx, so -rx becomes (K1/K2), independent of concentration. The reaction is therefore zero order with rate constant K1/K2.
