It takes 5.89 s for the concentration of NH_3 to decrease by 88.0%.

Explanation:

$2NH_3(g)\rightarrow N_2(g)+3H_2(g)$

As the units of rate constant is $M^{-1}s^{-1}$ , the kinetics must be second order.

Integrated rate law for second order kinetics is given by:

$\frac{1}{a}=kt+\frac{1}{a_0}$

a_0 = initiaal concentration = 0.590 M

a= concentration left after time t = $0.590-\frac{88}{100}\times 0.590=0.0708M$

$\frac{1}{0.0708}=2.11\times t+\frac{1}{0.590}$

t=5.89s

Thus it takes 5.89 seconds for the concentration of NH_3 to decrease by 88.0%.
