Question 1

Multiple Choice

Given that ΔH°= -311 kJ for the hydrogenation of acetylene,C2H2:
H-C=C-H(g) + 2 H2(g) → CH3-CH3(g)
And the following bond dissociation energies,estimate a value for the C-to-C triple bond dissociation energy. Given that ΔH°= -311 kJ for the hydrogenation of acetylene,C<sub>2</sub>H<sub>2</sub>: H-C=C-H(g) + 2 H<sub>2</sub>(g) → CH<sub>3</sub>-CH<sub>3</sub>(g) And the following bond dissociation energies,estimate a value for the C-to-C triple bond dissociation energy. A) 1050 kJ/mol B) 833 kJ/mol C) 807 kJ/mol D) 397 kJ/mol
