Practice question · Numerical answer
When is doubled, the rate of a reaction increases by a factor of 4. What is the order with respect to A?
Hints
- Write the factor as 2 raised to the order.
- Solve 2^m = 4.
Show the answer
2
Why
The rate multiplies by , so gives , second order in A. Its half-life would then depend on the starting concentration, unlike a first-order reaction.
