All of the statements are true for spontaneous reactions except: a) the reaction rate is determined by the value of ΔG. b) if the enthalpy change is unfavorable, they occur at a high temperature. c) the value of ΔG is unaffected by a catalyst. d) the value of ΔG is less than zero. e)they are said to be exergonic.

Respuesta :

Answer:

A is false

Explanation:

A is false.

● activation energy affects the rate of a reaction and catalyst affects the rate of reaction too

ΔG (change in free energy) tells if a reaction is spontaneous or not
