Nitric acid can be manufactured in a multi-step process, during which nitric oxide is oxidized to create nitrogen dioxide. 2no (g) + o2 (g) → 2no2 (g)
calculate the standard reaction enthalpy for the above reaction using the following thermodynamic data.
n2 (g) + o2 (g) → 2no (g) ∆h˚1 = 180.5 kj
n2 (g) + 2o2 (g) → 2no2 (g) ∆h˚2 = 66.4 kj
