Question

For the reaction $A\to B$, identify the correct sequence of steps for the calculation of average rate of reaction.
(a) Plotting a graph of concentration of 'A' at various time intervals.
(b) Identification $C_2$ and $C_1$ at different time intervals $t_2$ and $t_1$ respectively by reading the graph.
(c) Calculation of $\frac{C_2-C_1}{t_2-t_1}$.
(d) Finding out the experimental values of concentrations of 'A' at regular intervals.

• A. dbca
• B. dabc
• C. cbad
• D. abcd

Answer 1

The correct option is B dabc

Correct sequence of operations is:
(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 $\frac{C_2-C_1}{t_2-t_1}$.
