NEETChemistryChemical Kinetics
For a reaction A + B → Products, the rate law is Rate = k[A][B] 3/2 Can the reaction be an elementary reaction? Explain.
Options
- ADuring an elementary reaction, the number of atoms or ions colliding to react is referred to as molecularity.
- BYes,this reaction is an elementary reaction because order is fractional according to rate law
- CNo,this reaction is not an elementary reaction because the rate law indicates the order of the reaction is an
- DNone of the above
Correct answer
A. During an elementary reaction, the number of atoms or ions colliding to react is referred to as molecularity.
Step-by-step solution
Correct Option is : (A) During an elementary reaction, the number of atoms or ions colliding to react is referred to as molecularity. Had this been an elementary reaction the order of reaction with respect to B would have been 1, but in the given rate law it is (3/2) . This indicates that the reaction is not an elementary reaction.
