Question

The rate of a reaction is found to double when the concentration of one reactant is quadrupled (increased by a factor of 4). The order of the reaction with respect to this reactant is __________

one quarter (1/4)
First
one half (1/2)
Second

Answer 1

Half (1/2)

Step-by-step explanation:

according to R = k[A].

when A is quadrupled and reaction order is half,it becomes.

R= k[4A]^1/2

R=k2[A]^1/2.

it aligns with the question.
