At 300 K, about 0.40 % of collisions in a gas sample have energies equal to or greater than 75 kJ mol−1. When the temperature is raised to 310 K, which estimate best describes how this percentage changes?
a) About 0.44%—a modest 3% rise that mirrors the temperature increase.
b) About 0.13%—the fraction is predicted to fall as T rises.
c) About 1.0%—a bit more than double because the high-energy tail is very temperature-sensitive.
d) About 0.40%—essentially unchanged for such a small ΔT.
