Explanation / Answer

part D

second order kinetics.

K2 = x/t*(a)*a0

k2 = 1.68 M-1.h-1

x = reacted = ? M

a0 = initial no of concentration of X2Y = 0.1 M

a = concentration after time,13 hr = a0-x M

t = time = 13 hr

1.68 = x/(13*(0.1-x)*0.1)

x = 0.0685

a = concentration after time,13 hr = a0-x

= 0.1-0.0685

= 0.0315 M
