Use AGⓇ =AH°-TAS and assume AH° and AS are independent of temperature. P Flag question (Theis...
For a particular reaction, AH = -14.20 kJ/mol and AS = -198.5 J/(mol.K). Calculate AG for this reaction at 298 K. AG = 73.35 kJ/mol
a) Determine AG for the following reaction at 25C: N2O2(g) ---> 2NO2(g) AH = +55.3 kJ; AS = +175.7 J/K b) is the reaction spontaneous under standard state conditions? c) at what temperature will the reaction become spontaneous? ♡ a) 2.94 kJ; b) no; c) 315 K a)-52.3 kJ; b) yes; c) at no temperature a) 50.9 kJ;b) yes; c)-750 K a) -4.34 kJ; b) no; c)-315 K
AG°= AH-TAS AG=AGº+RTinQ where R=8.314 J/mol K 1. Calculate AGº for the following reaction at 25 °C if AH°= -1854 kJ/mol; AS°= -236 J/mol K CH-COCH3(g) + 402(g) → 3C02(g) + 3H2O(1) 2. NH.NO, dissolving in water is a spontaneous process. As it dissolves, the temperature of the solution decreases. Based on this, what must the signs (positive or negative) of AG, AH, and AS be?
