Heat of vaporization is the heat required to vaporize unit mass of a substance at it's boiling point. The heat of vaporization or condensation of water is 2257 J/g.
It means that 1 g of water involves 2257 J energy during condensation or vaporization at its boiling point (100 C)
Given mass of water vapor that is condensing = 11.2 g
Calculating the heat released when 11.2 g of water vapor condenses in to liquid water at 100:
Rounding the final answer 25,278 J to three significant figures we get, 25,300 J
Therefore the correct answer is E. 25,300 J
Answer: The reaction is endothermic.
Explanation:
Endothermic reaction : It is a type of chemical reaction where the energy is absorbed from the surrounding. In the endothermic reaction, the reactant have less energy than the energy of products
In endothermic reaction, enthalpy terms is located on the reactant side.
Example:
Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactants are more than the energy of products
In exothermic reaction, enthalpy terms is located on the product side.
Example:
