(circle one)                               The reaction is not spontaneous at any temperature The reaction is spontaneous at all temperatures The reaction will only be spontaneous at low temperatures The reaction will only be spontaneous at high temperatures e)  Let's just say, ΔHº = -241.8 kJ and ΔSº = -88.8 J K-1.  (Ignore ΔGº). Assuming that ΔHº = ΔH and ΔSº = ΔS at all temperatures, calculate the temperature criterion for spontaneity.  That is, indicate the minimum or maximum temperature required for spontaneity (e.g. T > ### or T

Oliviа hаs twо primаry general liability pоlicies in place. Pоlicy A has a $2,000,000 limit and Policy B has a $500,000 limit. The policies specify contribution by equal shares as the method of sharing. If Olivia should become responsible for a $3,000,000 liability loss to which both policies apply, how much will each insurer contribute toward the loss?
