Question

For a hypothetical reaction $A⟶B$,it is found that the rate constant=$x{s}^{-1}$.By what factor the rate is increase if the initial concentration of $A$ is tripled?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is A 1

Unit of rate constant is $s^{-1}$. So, It's a 1st order reaction.

It is independent of the concentration.

Thought the initial concentration of $A$ is tripled, The rate increases by a factor '1'.

So Option $A$ is correct
