The units for the rate constant and the rate of reaction are same for a reaction. What will be the order of the reaction?
- A First
- B Zero
- C Second
- D Third
Answer & Solution
Correct Answer
(B) Zero
Step-by-step Solution
Detailed explanation
B
Unit of rate constant \((k)=(\text { conc })^{1- n }( s )^{-1}\)
\(n =\) order of the reaction
The rate law of the reaction is
Rate \(=k\) [Reactant] \({ }^{ n }\)
For unit of Rate \(=\) Rate constant \((k) ; n\) should be equal to 0
\(\therefore\) Order is zero.
