Problem Details

A friend studies a first-order reaction and obtains the following three graphs for experiments done at two different temperatures.
A graph has time on the x-axis and natural log of the concentration of A on the y-axis; both are unscaled. Lines 1, 2 and 3 decrease from the y-axis, with 2 and 3 starting at the same point and 1 starting lower. 3 has the flattest slope and 1 and 2 are parallel.

Which graph probably represents the lower temperature? How do you know?
