Gas P decomposes to form gas Q. xP → yQ Two experiments are carried out to investigate the rate of reaction. The conditions are the same except that two different temperatures, T1 and T2, are used. The results are plotted on graphs, drawn to the same scale. Which row is correct?

1. Ax = 2, y = 3, T1 is higher than T2
2. Bx = 2, y = 3, T2 is higher than T1
3. Cx = 3, y = 2, T1 is higher than T2
4. Dx = 3, y = 2, T2 is higher than T1
