Hints
For a certain reaction, the rate = \(k[A]^2[B],\) when the initial concentration of A is tripled keeping the concentration of B constant, the initial rate would be:
| 1. | increase by a factor of three |
| 2. | decrease by a factor of nine |
| 3. | increase by a factor of six |
| 4. | increase by a factor of nine |

The correct options for the rate law that corresponds to overall first order reaction is:
| 1. | \( Rate =k[A]^0[B]^2 \) | 2. | \( Rate =k[A][B] \) |
| 3. | \(Rate=k[A]^{1 / 2}[B]^2 \) | 4. | \(Rate =k[A]^{-1 / 2}[B]^{3 / 2}\) |

The given graph is a representation of the kinetics of a reaction.
The y and x axes for zero and first-order reactions, respectively are
The y and x axes for zero and first-order reactions, respectively are
| 1. | zero order (y=rate and x=concentration), first order (y=rate and x=t1/2) |
| 2. | zero order (y=concentration and x=time), first order (y=t1/2 and x = concentration) |
| 3. | zero order (y=concentration and x= time), first order (y=rate constant and x= concentration) |
| 4. | zero order (y=rate and x=concentration), first order (y=t1/2 and x = concentration) |
