विकल्प

• 2.5

• 2.0

• 1.5

• 0.5

Answer 1

The rate of a reaction increases sixteen times when the concentration of the reactant increases four times. The order of the reaction is 2.0.

Explanation:

r = k[A]ⁿ   ...(i)

n = order of the reaction

16r = k[4A]ⁿ   ...(ii)

Dividing eq. (ii) by eq. (i),

16 = 4n

n =2

Order of the reaction = 2
