Over a wide temperature range, the reaction, M2O3(s) + C(s) ® M(s) + CO2(g), is spontaneous at low temperatures but non-spontaneous at high temperatures. If we assume that, since the physical states do not change, the values of and are constant over this temperature range, we can then deduce that Question 11 options: 1) DeltaH < 0 and DeltaS > 0 2) DeltaH < 0 and DeltsS < 0 3) DeltaH > 0 and DeltaS < 0 4) DeltaH > 0 and DeltaS > 0 5) the information is insufficient to make any judgment as to the signs of DeltaH and DeltaS
