Calculate the average rate of decomposition of NH4NO2 by the reaction 2NH4O5(aq) --> N2(g) H2O(g) at the following time inter
igor_vitrenko [27]

Answer:

r=-0.033\frac{M}{s}

Explanation:

Hello!

In this case, since the average rate of reaction is computed as a change given by:

r=\frac{\Delta [NH_4NO_2 ]}{\Delta t}

In such a way, given the concentrations at the specified times, we plug them in to obtain:

r=\frac{(1.48M-4.12M)}{(330s-250s)}\\\\r=-0.033\frac{M}{s}

Whose negative sign means the concentration decreased due to the decomposition.

Best regards!
