Answer»

The
rate constant for the decomposition of N
2O5
at
various temperatures is given below:





























T/°C



0



20



40



60



80





0.0787



1.70



25.7



178



2140





Draw
a graph between ln
k
and 1/T
and
calculate the values of
A
and Ea.


Predict
the rate constant at 30º and 50ºC.
