Explanation / Answer

a)

Integrated rate law for zero order reaction is

[A] = -kt + [A]0

where,

t = time

k = rate constant

[A]= concentration at time t

[A]0 = Initial concentration

b) Half life of Zero order reaction obtained by the following equation

t1/2 = [A]0/2k

= 0.001M/2*(0.050Ms-1)

= 0.02s

c) Apply integrated Zero oreder rate law

   [A] = - kt + [A]0

   = - (0.050Ms-1) * 0.005s + 0.001M

= 0.00075M

So, after 0.005s elapsed, concentration of A is 0.00075

So, Concentration of A reacted = 0.00100 - 0.00075 = 0.00025M

concentration of B produced = Concentration of A reacted

Therefore,

Concentration of B after 0.005s elapsed = 0.00025M
