Determine the amount of heat (in kJ) given off when 2.23 multiplied by 104 g of ammonia are produced according to the following equation. Assume that the reaction takes place under standard-state conditions at 25.0°C.
N2(g) + 3 H2(g) 2 NH3(g) ΔH°rxn = -92.6 kJ
How many moles NH3 do you have in 2.23 x 10^4 g NH3? So moles NH3 x 92.6 kJ/mol = ??
