Question:medium

In the reaction: P + Q longrightarrow ?R + S The time taken for 75% reaction of P is twice the time taken for 50% reaction of P. The concentration of Q varies with time as shown in the figure. The overall order of the reaction is: 

Show Hint

For second-order reactions: t₇5% = 2t₅0% Zero-order reactions show linear concentration–time plots.
