is this true or false? i think its false because isnt it spontaneous if its positive
When (triangle i think its called delta) H for a reaction is large and positive, the reaction is not expected to be spontaneous.

change of heat, yeah then it requires heat which means it should be non-spontaneous . ..
Delta H is positive, the reaction is endothermic therefore not spontaneous.
delta G = delta H -TdeltaS.
Generally, but not always, if delta H is negative, then delta G is more likely to be negative, and the reaction will be spontaneous. But delta H can be + and the temperature can be high enough to make the TdeltaS term override the + delta H and delta G can be negative and the reaction spontaneous.
