Question
A reaction is first order in A and second order in B.
  1. Write the differential rate equation.
  2. How is the rate affected on increasing the concentration of B three times?
  3. How is the rate affected when the concentrations of both A and B arc doubled?
✓

Answer

1. $\frac{d x}{d t}= k [ A ]^1[ B ]^2$
2. If concentration of ' $B$ ' is tripled, then the rate will become 9 times.
3. When concentration of both $A$ and $B$ are doubled, then the rate will become 8 times.
