Rate constants for the reaction : \( \mathrm{NO}_{2}(\mathrm{~g})+\mathrm{CO}(\mathrm{g}) \rightarrow \mathrm{NO}(\mathrm{g})+\mathrm{CO}_{2}(\mathrm{~g}) \) are \( 1.3 \mathrm{M}^{-1} \mathrm{~s}^{-1} \) at \( 600 \mathrm{~K} \) and \( 26 \mathrm{M}^{-1} \mathrm{~s}^{-1} \) at \( 800 \mathrm{~K} \). [Given : \( \ln 10=2.3, \ln 2=0.7 \) ]
\( P \) Calculate :
(a) activation energy in \( \mathrm{KCal} / \mathrm{mol} \).
(b) rate constant at \( 1200 \mathrm{~K} \).
