Your answer is partially correct. For the chemical reaction Al203(s) + 3H2(g,p = 1 bar) 2AI(s) + 3H20(1) at T = 298 K, answer each of the following by doing a quantitative calculation of the appropriate thermodynamic function: (a) Is this a spontaneous reaction? AG°reaction i kJ. The reaction is not spontaneous. (b) Does the reaction absorb or release heat? ΔΗreaction - i kJ. The reaction absorbs + heat. (c) Are the products more or less dispersed than the reactants? AS° reaction i J/K. Entropy decreases ÷ so the products are more + dispersed than the reactants. eTextbook and Media Save for Later Attempts: 1 of 3 used Submit Answer
