When the concentration of a reactant of first order reaction is doubled, the rate of reaction…
When the concentration of a reactant of first order reaction is doubled, the rate of reaction becomes _________ times, but for a __________ order reaction, the rate of reaction remains the same.
Answer
Answer
AIBlanks: two; zero
two; zero. For a first order reaction rate $\propto [A]$, so doubling the concentration doubles the rate; for a zero order reaction the rate is independent of concentration.
