Q6. Given = –-92.4 kJ What is the standard enthalpy of formation of gas?
Answer : Option B
Explaination / Solution:
Standard Enthalpy of formation of NH3 is the energy change that take place when 1 mole of NH3 is formed from elements in standard state. For 2 moles of ammonia formation energy= –-92.4 kJ . For 1 mole energy =0.5 x–-92.4 kJ = -46.2 kJ
