According to the following reaction, how much energy is evolved during the reaction of 32.5 g B2H6 with excess Cl2? The molar ma

bonufazy [111]

Answer:

1640 kJ are involved in the reaction

Explanation:

In the reaction:

B₂H₆(g) + 6Cl₂(g) → 2 BCl₃(g) + 6HCl(g)

1 mol of B₂H₆(g) with 6 moles of Cl₂(g) produce 1396 kJ of energy.

Now if 32.5g of B₂H₆(g) react with excess Cl₂(g), moles involved in reaction are:

$32.5g B_2H_6\frac{1mol}{27.67g} = 1.175 moles$
