Calculate the energy required to produce 7.00 m CI2O7 on equation 2CI2 + 7O2 + 13O kcal->2CI2O7?

Question

a. 65 kcal

b. 130 kcal

c. 455 kcal

d. 7.00 kcal

Answer 1

Watch it close. The equation suggests that 130kCal is required to produce 2 moles of Cl2O7, i.e.

2 moles are produced with 130 kCal energy required

7 moles are produced with (130*7/2) kCal = 455kCal energy required

Ans : 455 kCal.
