What does a process require to be spontaneous at all temperatures? answer a catalyst and lower activation energy positive enthalpy and negative entropy changes a heat source and high activation energy negative enthalpy and positive entropy changes

negative enthalpy and positive entropy changes

Explanation:

= free energy change

= enthalpy change

T= temperature in Kelvin

= entropy change

, reaction is spontaneous

If

Thus reaction is spontaneous.

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

a is the correct answer
