Dependence of Rate on Temperature
CHXII04:CHEMICAL KINETICS

320274 The rate constant \({{\rm{k}}_{\rm{1}}}\) of a reaction is found to be double that of rate constant \({{\rm{k}}_{\rm{2}}}\) of another reaction. The relationship between corresponding activation energies of the two reactions at same temperature \(\left( {{{\rm{E}}_{\rm{1}}}} \right.\,\,{\rm{and}}\,\,{{\rm{E}}_{\rm{2}}}{\rm{)}}\) can be represented as

1 \(\mathrm{E}_{1}>\mathrm{E}_{2}\)
2 \(\mathrm{E}_{1} < \mathrm{E}_{2}\)
3 \(\mathrm{E}_{1}=\mathrm{E}_{2}\)
4 none

320275 The activation energy of a reaction at a given temperature is found to be \({\text{2}}{\text{.303 RT J mo}}{{\text{l}}^{{\text{ - 1}}}}\). The ratio of rate constant \((\mathrm{k})\) to the arrhenius factor (A) is:

1 0.01
2 0.1
3 0.02
4 0.001
CHXII04:CHEMICAL KINETICS

320276 Activation energy of a reaction is:

1 the energy released during the reaction
2 the energy evolved when activated complex is formed
3 additional amount of energy needed to overcome the potential barrier of reaction
4 the energy needed to form one mole of the product

320277 The rate constant for the first order decomposition of the ethylene oxide into \(\mathrm{CH}_{4}\) and \(\mathrm{CO}\) is described by \(\log \mathrm{k}\left(\mathrm{s}^{-1}\right)=14.34-\dfrac{12.5 \times 10^{4} \mathrm{~K}}{\mathrm{~T}}\)
Then the activation energy of the reaction is
