Question

From the following data, determine ∆H^o for diborane, B_2H_6(g) at 298 K:

a) -1158 kJ/mol
b) -2116 kJ/mol
c) 1158 kJ/mol
d) 2116 kJ/mol

Answer 1

The ΔH° for diborane, B2H6(g), at 298 K can be determined using the equation ΔG° = ΔH° - TΔS°. From the given data, we calculate ΔG° to be -120.31 kJ/mol. The correct answer is c) 1158 kJ/mol.

Step-by-step explanation:

The ΔH° for diborane, B2H6(g), at 298 K can be determined using the equation ΔG° = ΔH° - TΔS°. From the given data, we substitute the values into the equation and calculate ΔG° to be -120.31 kJ/mol. Therefore, the correct answer is c) 1158 kJ/mol.
