Q. The slowest step of the reaction in a multi-step reaction is called rate-determining step.

Why does the slowest step considered a rate determining step of the reaction?

Q. Assertion :Complex reaction takes place in different steps and the slowest step determines the rate of reaction. Reason: Order and molecularity of a reaction are always equal.

For a complex reaction ......... .

(a) order of overall reaction is same as molecularity of the slowest step
(b) order of overall reaction is less than the molecularity of the slowest step
(c) order of overall reaction is greater than molecularity of the slowest step
(d) molecularity of the slowest step is never zero or non-integer

Q. A chemical reaction procceds into the following steps,
Step I,

2 A ⇌ X (f a s t)

Step II,
