In an endothermic reaction products are <u>HIGHER </u>than reactants in potential energy and <u>LESS </u>stable.
Explanation:
Energy is input into the reaction in an endothermic reaction. This means the products are of a higher energy level than the reactants. Therefore the reaction increases Gibb's free energy and reduces entropy. Remember in thermodynamic stability involves an increase in entropy and a decrease in Gibbs free energy. Therefore the products are less stable than the reactants. This is why endothermic reactions do not occur spontaneously like exothermic reactions.
The correct answer is false. It is not chemical equilibrium when the forward rate of reaction is greater than the reverse rate of reaction. Instead, these two rates should be equal to achieve chemical equilibrium.
Just choice D.
If you find the number of atoms of each element, you will find that only choice D has the same amounts on each side of the equation.
Alteration of the physical form of a drug outside its label is compounding
It is called compounding according to some sources.
