Ber [7]

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

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 = \frac{130}{2}\times 12.00=780kcal

Thus 780 kcal are required to produce 12.00 mol of Cl_2O_7

Energy transferred per second in given area:
8000 x 3.9 / 10000
Energy transferred = 3.12 J

Using Planck's equation:
E = nhc/λ
n = (3.12 x 510 x 10⁻⁹) / (3 x 10⁸ x 6.63 x 10⁻³⁴)
n = 8 x 10¹⁸ photons
