Second Order Reaction MCQ - Practice Questions with Answers

Consider the reaction

For ssecond order reaction, the rate law is given as follows:

• Integrated Rate Law: Since it is a second order reaction, thus:
  
  Integrating both sides, we get:
  
  
  where, A_o is the initial concentration of A at time t = 0
  A is the remaining concentration of A after time 't'
  
  
  
  
  
  
  
  
   
• Half-life(t_1/2): We know that the half-life for a reaction is the time when the concentration of the reactant(A) is half of tis initial value.
  Thus, at time t = t_1/2, A = A_o/2
  From equation (i) we have:
  
  
  
  
  
  
  This is the half-life for the second-order reaction.
