Ammonia reacts with oxygen according to the equation: 4NH3(g)+5O2(g)→4NO(g)+6H2O(g) ΔHrxn=-906 kJ Part A Calculate the heat (in kJ) associated with the complete reaction of 284 g of NH3. Express your answer with the appropriate units.

Expert Solution

According to the balanced eqation and heat of reaction shown:

Heat associated with the reaction of 4 moles of NH3 (4 x 17 g = 68 g) with oxygen = -906 kJ

So, the heat associated with the reaction 1 g of NH3 with oxygen = -906/68 kJ

So, the heat associated with the reaction 284 g of NH3 with oxygen = -906 x 284/68 kJ

= 3783.88 kJ
