The rate constant for a particular zero-order reaction is 0.075 M s-1. If the initial concentration of reactant is 0.537 M it ta
Phoenix [80]

Answer : It takes time for the concentration to decrease to 0.100 M is, 22.4 s

Explanation :

Formula used to calculate the rate constant for zero order reaction.

The expression used is:

\ln [A]=-kt+\ln [A_o]

where,

[A_o] = initial concentration = 0.537 M

[A] = final concentration = 0.100 M

t = time = ?

k = rate constant = 0.075 M/s

Now put all the given values in the above expression, we get:

\ln (0.100)=-0.075\times t+\ln (0.537)

t=22.4s

Therefore, it takes time for the concentration to decrease to 0.100 M is, 22.4 s
