Question 32

A chemical engineer is studying the gas-phase decomposition of dinitrogen pentoxide into nitrogen dioxide and oxygen:

2N2O5(g)→4NO2(g)+O2(g) 2\text{N}_2\text{O}_5\text{(g)} \rightarrow 4\text{NO}_2\text{(g)} + \text{O}_2\text{(g)} 2N2​O5​(g)→4NO2​(g)+O2​(g)

She measures the rate of reaction at 280 K and then at 350 K, noting that the rate is substantially higher at 350 K.

Explain, in terms of collision theory, why the rate of reaction increases when the temperature is raised from 280 K to 350 K.
