5 of 15 A reaction is non-spontaneous. What can you conclude about the reverse reaction? O It is spontaneous. It must be exothermic O It must have an increase in entropy O It is in equilibrium. 6 of 15 Based on the AG calculation, a student determined that a synthesis reaction should be spontaneous. When the student tries out the reaction, however, nothing happens. Which explanation is most plausible? O the student probably made a mistake in the calculation O...

A reaction that has a positive AH and a positive AS will be spontaneous at high temperatures spontaneous at low temperatures spontaneous at all temperatures nonspontaneous at all temperatures QUESTION 6 Which of the following statements is FALSE? Keg for a reaction written in reverse is the reciprocal of the key for the forward reaction A reaction quotient (Q) larger than Keq means that the reaction will shift toward reactants Chemical equilibrium indicates that reactants and products are present in...

Then, he measures the reaction enthalpy AH and reaction entropy AS of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the under the conditions the engineer has set up, the reaction is spontaneous, the spontaneous because the system is at equilibrium.
