The average rate of reaction will upto 40s will be V₃/40.
The graph will be a straight line till V3 or at t = 40 (Given)
Equation of a line = y = mx + c, where m is the slope to be determined by equation.
m - y2-y1/x2-x1, where (y2-y1) and (x2-x1) are the points on a line
On substituting the value -
V3-V1/t3-t1
Thus, slope = V3/40.
