Assertion (A) : For: aA+bB rarr Product....

Assertion (A) : For: `aA+bB rarr` Product. The order of reaction is equal to `(a+b)`.
Reason (R ): Rate of reaction `=k[A]^(a)[B]^(b)`.

Text Solution

Verified by Experts

The correct Answer is:
b
Rate of reaction = `k [A]^(a) [B]^(b) therefore` Order of reaction = a + b .
