# Worksheet: Second-Order Rate Plots

In this worksheet, we will practice plotting concentration–time data for second-order reactions to calculate the rate constants and initial concentrations.

**Q1: **

The concentration of a reactant A was monitored during the course of a reaction. The data were plotted on a graph of against time. If the reaction is of the second order with respect to A, what is the initial concentration of A in terms of the gradient of the plot and the -intercept ?

- A

- C
- D
- E
