Nothing can be said about reaction rate from the information given.

The rate is faster.

The rate is slower.

The rates are equal.

The rate of the reaction is only faster when the temperature is low.

exergonic and spontaneous

exergonic and non-spontaneous

endergonic and spontaneous

endergonic and non-spontaneous

Not enough information given.

Metabolism in brown fat cells

ATP hydrolysis during muscle contraction

ATP-hydrolyzing substrate cycles

Sweating

Vasodilation of blood vessels

A spontaneous reaction always happens quickly

A negative enthalpy is favorable for a spontaneous reaction

A spontaneous reaction can still occur with a large decrease in entropy

A nonspontaneous reaction will proceed spontaneously when reversed

A spontaneous reaction proceeds in the forward direction with a negative Gibbs free energy value
