Question

Calculate the energy required to produce 7.00 mol Cl2O7 on the basis of the following balanced equation. 2Cl2(g) + 7O2(g) + 130 kcal --> 2Cl2O7(g) Select one: a. 7.00 kcal b. 65 kcal c. 130 kcal d. 455 kcal

Answer 1

Step-by-step explanation:

As the given chemical reaction equation is as follows.

`2Cl_(2)(g) + 7O_(2)(g) + 130 kcal \rightarrow 2Cl_(2)O_(7)(g)`

Also, it is given that for 2 moles the energy required is 130 kcal. This means that energy required for 1 mole is calculated as follows.

1 mole =
`(130 kcal)/(2)`

= 65 kcal

Hence, energy required for 7 moles will be calculated as follows.

Energy required =
`7 * 65 kcal`

= 455 kcal

Thus, we can conclude that energy required to produce 7.00 mol
`Cl_(2)O_(7)` on the basis of given reaction is 455 kcal.
