Assertion :Rate of reaction doubles when concentration of reactant is doubled if it is a first order reaction.Reason :Rate constant also doubles.

Options:

Answer:

Solution:

For first order reaction, $Rate_{1} = k [A_{1}]$ According to question, $[A_{2}] = [2 A_{1}]$ $∴ Rate_{2} = k [2 A_{1}] \Rightarrow Rate_{2} = 2 Rate_{1}$ For a given reaction, rate constant is constant and independent of the concentration of reactant.
