If the concentration of nucleophile increases does the reaction go faster

Depends on the situation. If the nucleophile is already in excess, then no the reaction will not occur faster 

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.

The answer is yes b ffgnbsfgnbnfgbnfgsnb
