Question

Transcribed Image Text:H2 (g) + Cl2 (g) –→ 2 HCI (g)
Using the following information, calculate AHrxn for the reaction above:
NH3 (g) + HCI (g) → NH,CI (s) AHxn = -176 kJ/mol
N2 (g) + 4 H2 (9) + Cl2 (g) → 2 NH,CI (s) AHxn = -628 kJ/mol
|
NH3 (g) → 1/2 N2 (g) + 3/2 H2 (g) AHxn= 46 kJ/mol
number or fraction only kJ/mol
