If AG < 0 for a reaction, which of the following is/are true? Select all that apply. There will be no net change in the amounts of reactants or products. The reaction is spontaneous in the forward direction. The reaction is spontaneous in the reverse direction. The reaction is at equilibrium. The reaction will proceed to form more products. The reaction will proceed to form more reactants.

Calculate AH for the following reaction using the given bond dissociation energies. >co,g)+2H,0(g) AH° (kJ/mol) CHg)20,g) Bond 142 О-О Н-О 459 С-Н 411 799 O O 498 С-О 358 Number ΔΗ. kJ/ mol This reaction is endothermic exothermic
A process at constant T and P can be described as spontaneous if AG <0 and nonspontaneous if AG> 0. Over what range of temperatures is the following process spontaneous? Assume that gases are at a pressure of 1 atm. (Hint: Use the data below to calculate AH and AS [assumed independent of temperature and equal to AH° and AS°, respectively] and then use the definition of AG.) 2 MnO2(s) 02(g) 2 MnO(s) AH (kJ mol) -520.0 -385.2 s° (J...
