Question 1

According to the following reaction, how much energy is evolved during the reaction of 32.5 g B2H6 and 72.5 g Cl2? The molar mass of B2H6 is 27.67 g mol-1.

B2H6(g) + 6Cl2(g) → 2BCl3(g) + 6HCl(g)DrH° = -1396 kJ

◦ 429 kJ
◦ 1430 kJ
◦ 3070 kJ
◦ 1640 kJ
◦ 238 kJ

Question 2

According to the following reaction, how much energy is evolved during the reaction of 2.50 L B2H6 and 5.65 L Cl2 (both gases are initially at STP)? The molar mass of B2H6 is 27.67 g mol-1.

B2H6(g) + 6Cl2(g) → 2BCl3(g) + 6HCl(g)DrH° = -1396 kJ

◦ 352 kJ
◦ 508 kJ
◦ 156 kJ
◦ 57.8 kJ
◦ 215 kJ
