For a given reaction, H = +35.5 kJ/mol and S = +83.6 J/Kmol. The reaction is spontaneous ________. Assume that H and S do not vary with temperature. at T < 425 K at T > 425 K at all temperatures at T > 298 K at T < 298 K
-254/mol K. When is this reaction spontaneous (assuming that and AS do not vary as the temperature changes). For a particular reaction, the value of AH-43.6 kJ/mol and as ALT> 191 At T< 464K ALT<191K This reaction is spontaneous at all temperatures This reaction is not spontaneous at all temperatures
1. A reaction has AH = 100 kJ/mol and AS = 250 J/mol K. a. Is the reaction spontaneous at room temperature? b. If not, under what temperature conditions will it become spontaneous? 2. Consider the following reaction at 298 K: N204(g) = 2NO2(g) KP=0.142 What is the standard free energy change at this temperature? Is the reaction spontaneous at this temperature?
For a particular reaction, AH = -16.1 kJ/mol and AS = -21.8 J/(mol-K). Assuming these values change very little with temperature, at what temperature does the reaction change from no to spontaneous in the forward direction? 5 T= Is the reaction in the forward direction spontaneous at temperatures s greater than or less than the calculated temperature? less than O greater than
B. For this reaction, AH=-54kJ/mol and AS=231/K•mol. At what temperatures is this reaction spontaneous? 23 kJ/kinol)
