For the reaction A to B , identify the correct sequence of steps for thecalculation of average rate of reaction. (1) plotting a graph of concentration of 'A' at various time intervals. (2) identification of C_(2) and C_(1) at different time interval t_(2) and t_(1) , respectively by reading the graph (3) Calculation of (C_(2)-C_(1))/(t_(2)-t_(1)) (4) finding out the experimental values of concentratiions of 'A' at regular intervals

4,2,3,1
4,1,2,3
3,2,1,4
1,2,3,4

Solution :(i) FINDING out the experimental values of the concentrations of A at regular intervals.
(II) plotting a graph of CONCENTRATION of A at various times
(III) identification of `C_(2) and C_(1)` at different time intervals `t_(2) and t_(1)` by reading the graph
(iv) calculation of `(C_(2)-C_(1))/(t_(2)-t_(1))`
