Match the following.
-A process or reaction that has a positive value of ΔG

Question

Quizplus · Accepted Answer

Endothermic reactions have a positive ΔG value, meaning they require energy to occur. Endergonic reactions are also characterized by a positive change in enthalpy and a negative change in entropy.

Answer: A
 Exergonic reactions have a negative ΔG value, meaning they release energy. These reactions typically involve the breakdown of larger molecules into smaller ones, and are characterized by a negative change in enthalpy and a positive change in entropy.

Answer: E
 Activation energy is the energy required to "activate" a reaction and allow it to proceed. This energy barrier must be overcome before the reaction can occur, and is typically supplied by heat, light, or some other form of energy.

Answer: F
 Chemical equilibrium is reached when the rate of the forward reaction is equal to the rate of the reverse reaction, resulting in no net change in the concentrations of products and reactants. At equilibrium, the ΔG value is zero, meaning there is no free energy available to drive the reaction in either direction.
