Integrated rate equation for zero order given below
[A] = [A0]- Kt
Given
Rate constant K= 4.80 x10^-4 M/s
Time taken t = 45 s
final concentration [A] = 5.50 x10^-2 M
Initial concentration [A0] = ??
plug in nunbers in the given formula
5.50 x10^-2 M = [A0] -4.80 x10^-4 M/s*45 s
[A0] = 5.50 x10^-2 M + 2.16 x1)6-2 M = 7.66 x10^-2 M
Initial concentration [A]0 =7.66 x10^-2 M
