Calculate δh⁰298 (in kj) for the process p(s) + 5/2 cl2(g) → pcl5(g) from the following information.
p(s) + 3/2 cl2(g) → pcl3(g) δh⁰298 = −287 kj
pcl3(g) + cl2(g) → pcl5(g) δh⁰298 = −88 kj

for the process is -375 kJ

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
