A student draws a graph of the volume of gas produced against time. How can the rate of reaction at 40 s be found from this graph?

[1]
A

By dividing the total volume of gas by 40 s40\ \text{s}40 s

B

By reading the volume of gas collected at 40 s40\ \text{s}40 s

C

By measuring the area under the curve at 40 s40\ \text{s}40 s

D

By finding the gradient of a tangent at 40 s40\ \text{s}40 s
