For a reaction A \(\rightarrow\) B, the rate law is given by:
\[
\text{Rate} = k[\text{A}]^2
\]
If the concentration of A is increased by a factor of 3, by what factor does the rate of the reaction increase?
Show Hint
The rate of reaction is proportional to the concentration of reactants raised to the power of their respective order. For a reaction where the rate law is \( \text{Rate} = k[\text{A}]^2 \), a 3-fold increase in concentration results in a 9-fold increase in the rate.
