Dependence of Rate on Concentration
CHXII04:CHEMICAL KINETICS

320137 Which of the following statement is NOT true for a reaction having rate law \(\mathrm{r}=\mathrm{k}\left[\mathrm{H}_{2}\right]\left[\mathrm{I}_{2}\right]\) ?

1 The reaction is first order in \(\mathrm{H}_{2}\)
2 Overall order of reaction is 1
3 The reaction is first order in \({{\text{I}}_{\text{2}}}\)
4 Overall order of reaction is 2
CHXII04:CHEMICAL KINETICS

320138 Assertion :
The order of reaction may be defined as the sum of the powers which the concentration terms are raised in order to determine the rate of reaction gives the total order of reaction
Reason :
The number of molecules whose concentrations determine the rate of reaciton at a given temperature is called order of reaction.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

320140 Higher order \((>3)\) reactions are rare due to:

1 Loss of active species on collision
2 shifting of equilibrium towards reactants due to elastic collisions
3 Low probability of simultaneously collision of all the reacting species
4 Increase in entropy and activation energy as more molecules are involved.
