Calculate the heat of reaction for the combustion of nitrogen monoxide gas, NO, to form nitrogendioxide, NO2 , as given in the following thermochemical equation:
NO(g) + 1/2 O2 → NO2(g)
Given:(a) 1/2 N2(g) + 1/2O2(g) → NO(g) ∆Hro = 90.29kJ/mol(b) 1/2N2(g) + O2(g) → NO2(g) ∆Hro = 33.2 kJ/mol
During the experiment, when calculating for ΔH using the formula ΔH = C x ΔT, can we calculate the ΔH without measuring the amount of water that we put inside the calorimeter? Explain why or why not. (max of 5 sentences)
