Question

The rate law expression for four reactions are give below. In which case, the percentage increase in the rate of reaction would be maximum when the concentration of A is doubled?

• A. $r=k\left[A\right]$
• B. $r=k[A{]}^{\frac{3}{2}}$
  
  
• C. $r=k[A{]}^{\circ }$
• D. $r=k[A{]}^2$

Answer 1

The correct option is D $r=k[A{]}^2$

Larger the order of reaction more the percent increase in the rate of reaction for a given increase in concentration.
