Onsider the following generic reaction for which Kp = 5.51 × 105 at 25°C: 2R(g)+A(g)⇌2Z(g) What is the value of Kc for the reaction at the same temperature? View Available Hint(s) Consider the following generic reaction for which Kp = 5.51 × 105 at 25°C: What is the value of Kc for the reaction at the same temperature? 2.25 × 104 5.51 × 105 1.35 × 107 1.37 × 109

There are two types of Reactions,

Endothermic reactions are the type chemical reaction in which the reactants absorb heat energy from the surroundings. The energy of reactants is more than the energy of product

Exothermic reactions are the type of chemical reactions in which release of energy takes place in the form of heat or light. In an exothermic reaction, energy is released. The energy of the products is less than the energy of the reactants.

The key word is "RELEASE". The reaction in which energy is released is the Exothermic reaction thus the Option B that is EXOTHERMIC REACTION is correct.

It is asking that which process stores the energy that means it is asking which process undergoes endothermic reaction. The answer is Option C that is PHOTOSYNTHESIS is correct.

Because, sunlight is being absorbed during the reaction and according to the definition of endothermic reaction if heat is being absorbed it is termed as an endothermic reaction.
