The inversion of cane sugar proceeds with half life of 500 minute at pH = 5 for any concentration of sugar. However, if pH = 6, the half life changes to 50 minute. The rate law expression for the sugar inversion can be written as -

A

R = K(sugar)2 (H+)0

B

R = K(sugar)1 (H+)0

C

R = K(sugar)1 (H+)1

D

R = K(sugar)0 (H+)1

Answer

R = K(sugar)1 (H+)0

Explanation

Solution

r = K(sugar)1 (H+)m ; t12∝[sugar]0t_{\frac{1}{2}} \propto \lbrack sugar\rbrack^{0}
