Problem

Rate constants for the reaction

\text{NO}_2(\text{g}) + \text{CO}(\text{g}) \rightarrow \text{NO}(\text{g}) + \text{CO}_2(\text{g})

are given below. At 700 K,

k = 1.30\text{ mol dm}^{-3}\text{ s}^{-1}

At 800 K,

k = 23.0\text{ mol dm}^{-3}\text{ s}^{-1}

Calculate the value of the activation energy in

\text{kJ mol}^{-1}
