A second-order irreversible elementary reaction 2A → products is carried out in a batch reactor. For a certain set of conditions, it is found that it took 20 min for a reaction to reach 60 percent completion. What would be the time required to reach the same degree of completion if (a) the initial concentration of A were doubled and (b) the reaction rate constant were doubled?

Question

A second-order irreversible elementary reaction 2A → products is
carried out in a batch reactor. For a certain set of conditions, it
is found that it took 20 min for a reaction to reach 60 percent
completion. What would be the time required to reach the same
degree of completion if (a) the initial concentration of A were
doubled and (b) the reaction rate constant were doubled?
