Given the equation: I + I → I2 + 35 kcal This equation shows that the formation of an iodine molecule is an A) endothermic process in which energy is absorbed B) exothermic process in which energy is released C) exothermic process in which energy is absorbed D) endothermic process in which energy is released

A) endothermic process in which energy is absorbed

Step-by-step explanation:

A thermochemical reaction equation is a chemical reaction equation in which the enthalpy of reaction is written after the symbols of reactants and products.

The importance of thermochemical reaction equations is that they show us whether energy was absorbed or evolved in a reaction as well as the magnitude of energy absorbed or evolved.

When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. When the enthalpy of reaction is negative, the reaction is exothermic and energy is evolved or released.

The enthalpy of the reaction  I + I → I2 + 35 kcal is positive hence the reaction is an endothermic process in which energy is absorbed.
