Question:

The order of reaction with rate law expression, $\frac{d[R]}{dt} =-k$, is

Options:

0

1

2

3

Correct Answer:

0

Explanation:

The correct answer is Option (1) → 0

The rate law is:

$-\frac{d[R]}{dt} = k$

Since the rate is independent of the concentration [R], this corresponds to a zero-order reaction.
