The rate constants for decomposition of acetaldehyde have been measured over the temperature range $700 - 1000K$ . The data has been analysed by plotting $lnk$ vs $\dfrac{{10}^{3}}{T}$ graph. The value of activation energy for the reaction is ${kJmol}^{- 1}$ . (Nearest integer) (Given : $R = 8 . 31J{K}^{- 1}{mol}^{- 1}$ )

k = Ae - E _ a RT lnk = lnA - E _ a RT lnk = lnA + [ - E _ a 1000R ](1000)/(T) Slope = - E _ a 1000R = - 18 . 5 E _ a = 18 . 5 × 1000 × 8 . 31 = 153 . 735 × 10 ^ 3 J = 154KJ
