In which case is a process spontaneous at any temperature? delta H : Negative delta s : Positive 6. For the reaction: C3H8(g) + 5O2(g) ->3CO2(g) +4H2O(l) Calculate the delta G at 298K given the delta G, KJ/mol of C3H8(g)=-23.47; O2=0; CO2=-394.4; H2O(l)=-273.13 The answer: -2155 KJ 7. In an electrochemical cell, Q=0.0010 and K=0.10. Which is true of Ecell and E^ocell? The answer: Ecell is positive and E^o cell is negative
