STANDARD Chemistry Order of Reaction MCQ Question with Solution

What will be the rate equation for the reaction 2X + Y → Z, if the order of the reaction is zero?

A

Rate = k[X] [Y]

B

Rate = k

C

Rate = k[X]⁰ [Y]

D

Rate = k[X] [Y]⁰

Option B

For a zero-order reaction, the rate is independent of the concentration of reactants. Therefore, the rate equation is simply Rate = k.
