for exothermic reactions why is q positive and for endothermic reactions why is q negative?
if q is the heat required then shouldn't endothermic reactions have a positive q because endothermic reactions require heat?
relationship between endothermic/exothermic and q

Re: relationship between endothermic/exothermic and q
Other way around. exothermic is -q because you're releasing heat (i.e. the thing releasing heat is losing energy, so it's losing q). endothermic is +q for the opposite reason.
