A reaction is spontaneous. What can you conclude about the reverse reaction?
It must be endothermic.
It is non-spontaneous.
It must have a decrease in entropy.
It is in equilibrium.
Spontaneous reaction is the one which occurs on its own without any external aid.
The spontaneous reaction cannot be endothermic as it requires energy to be supplied.
Spontaneous reaction results in increase in entropy. And the free energy change will be zero for reaction in equilibrium. For spontaneous reaction, free energy change is negative.
None of the options given by you are true for a spontaneous reaction.

1. A reaction is spontaneous. What can you conclude about the reverse reaction? It must be endothermic. It is non-spontaneous. It must have a decrease in entropy. It is in equilibrium. 2. ∆G is most affected by the presence of a catalyst the magnitude of the enthalpy the magnitude of the entropy the temperature
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...

An endothermic reaction with positive entropy change can be spontaneous only at low temperatures True or false
A reaction is non-spontaneous. Increasing the temperature can: a.make it endothermic b.change the value of ∆H c.change the sign of ∆G d.change the value of ∆S
What can you say about a reaction that has a positive enthalpy value and positive entropy value? (choose all that are correct) the reaction is spontaneous at low temperatures the reaction is spontaneous at high temperatures the reaction has a favorable enthalpy the reaction has an unfavorable entropy the reaction is never spontaneous the reaction has a favorable entropy the reaction is always spontaneous the reaction has an unfavorable enthalpy
