Question

NEED HELP PLEASE I AM GOING TO FAIL

A chemical reaction has an increase in entropy and a decrease in enthalpy. What is known about the spontaneity of the reaction?
spontaneous at high temperatures, nonspontaneous at low temperatures
nonspontaneous at high and low temperatures
spontaneous at low temperatures, nonspontaneous at high temperatures
spontaneous at high and low temperatures

Answer 1

spontaneous at low temperatures, nonspontaneous at high temperatures

Answer 2

The correct option is this: SPONTANEOUS AT HIGH AND LOW TEMPERATURES.
There are two basic factors which determine whether a reaction will be spontaneous or not, these are the entropy and the enthalpy change. Different reactions have different entropy and enthalpy values. For a reaction that has an increased entropy and a decreased enthalpy, the chemical reaction will be spontaneous at all temperatures.
