... 4. This is when a spontaneous reaction has a + ∆H and a + ∆S. The reaction is spontaneous because of its ∆S, so ∆S drives the reaction. 5. a. balance it first! ∆S is probably − because there are more gaseous reactants than products. ∆H is − because this is a combustion reaction and they are always e ...
