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