Under certain conditions the rate of this reaction is zero order in dinitrogen monoxide with a rate constant of ·0.0080Ms−1: 2N2
weqwewe [10]

Answer:

t=1.875s

Explanation:

Hello,

In this case, for the given reaction, the concentration of dinitrogen oxide is quantified as:

\frac{dC_{N_2O}}{dt}=r_{N_2O}

Considering that in molar units (M), the initial and final concentration of dinitrogen oxide are:

C_{N_2O,initial}=\frac{150.0mmol}{5.0L}*\frac{1mol}{1000mmol}  =0.03M\\\\C_{N_2O,final}=\frac{75.0mmol}{5.0L}*\frac{1mol}{1000mmol} =0.015M

Now, since the rate is zeroth order in dinitrogen oxide, it depends on the rate constant only:

\frac{dC_{N_2O}}{dt}=-k

Thus, by integrating from the initial concentration to the final concentration:

\int\limits^{0.015M}_{0.03M} {dC_{N_2O}} \, dx =-k\int\limits^t_0 {} \, dt

The time finally results:

t=\frac{0.015M-0.03M}{-0.0080M/s} \\\\t=1.875s

Best regards.
