A student measured the time taken for a reaction to finish at a range of different temperatures. He also measured the pH of his solutions to see if they varied. At 10°C the reaction took 1 minute 35 seconds. At 15°C it took 65 seconds, at 20°C 42 seconds, and at 25°C half a minute. The pH was exactly 7 for the 10°C result, 7.2 for the next, 7.1 for the third and 7.4 for the last (pH has no units). Record these results in a suitable table.
