Question

What is measured by the reaction rate?

the speed at which products form

the time required for a reaction to go to completion

the probability that a reaction will occur

Answer 1

The reaction rate is the speed at which products form, based on the rate of the slowest step in the mechanism.

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step explanation:

Rate of reaction is defined as the rate at which a chemical reaction occurs. That is, it tells how rapidly or slowly the products are formed.

Mathematically, Rate =
`(-\Delta [reactants])/(\Delta t)`

It also tells the number of successful collisions taking place.

Thus, we can conclude that the speed at which products form is measured by the reaction rate.
