Achemical reaction has an increase in entropy and a decrease in enthalpy. what is known about the spontaneity of the reaction?

Reaction is spontaneous at all temperatures.

Explanation:

According to Gibb's equation:

= Gibbs free energy

= enthalpy change

= entropy change

T = temperature in Kelvin

= +ve, reaction is non spontaneous

= -ve, reaction is spontaneous

= 0, reaction is in equilibrium

Thus when = -ve (decrease in enthalpy)

= +ve (increase in entropy)

Thus Reaction is spontaneous at all temperatures.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
