The rate constants for decomposition of acetaldehyde have been measured over the temperature range $\displaystyle 700$-$\displaystyle 1000$ K. The data has been analysed by plotting ln k vs $\displaystyle \frac{10^3}{\mathrm{~T}}$ graph. The value of activation energy for the reaction is \_\_\_\_ $\displaystyle \mathrm{kJ} \mathrm{mol}^{-1}$. (Nearest integer) (Given : $\displaystyle \mathrm{R}=8.31 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ )
