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...
