JEE Main Chemistry question

The order of the reaction, with respect to one of the reacting components Y, is zero. This implies that [AMU 2003]

(A)The reaction is going on at a constant rate
(B)The rate of reaction does not vary with temperature
(C)The reaction rate is independent of the concentration of YCorrect
(D)The rate of formation of the activated complex is zero

Answer: (C)

Solution

Zero order with respect to Y means the rate law contains , so changing the concentration of Y has no effect on the rate — the reaction rate is independent of the concentration of Y.
