Answer to Question #192372 in Organic Chemistry for Ritik

Question

The enthalpy of formation of NH3(g) as per the following reaction is -46.11 kJ/mol at 298 K.

Nâ‚‚(g) + 3Hâ‚‚(g) 2 NH3(g)

Calculate the value of enthalpy of formation of NH3(g) at 100 °C. The Co (JK mol) values are given as: N₂(g) 29.12; H2(g) = 28.82; NH3(g) = 35.06. Assume the given heat capacity values to be temperature independent in the range.

Answer 1

Value of enthalpy of formation of NH3(g);

=$-57.42kJ/mol$
