Question

11. Calculate the energy required to produce 12.00 mol of CI207 on the basis of the

following balanced equation.
2012(g) + 702(g) + 130 kcal yields 201207(9)

Answer 1

Answer: 780 kcal are required to produce 12.00 mol of
`Cl_2O_7`

Step-by-step explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and written along with reactants.

The balanced chemical reaction is:

`2Cl_2(g)+7O_2(g)+130kcal\rightarrow 2Cl_2O_7(g)`

According to stoichiometry :

2 moles of
`Cl_2O_7` are produced by absorption of energy = 130 kcal

Thus 12.00 moles of
`Cl_2O_7` are produced by absorption of energy =
`(130)/(2)* 12.00=780kcal`

Thus 780 kcal are required to produce 12.00 mol of
`Cl_2O_7`
