Assignment Help:
Nitrous acid (HNO2) is an unstable compound when prepared by the following reaction:
HCl (g) + NaNO2 (s) ? HNO2 (l) + NaCl (s).

As the product of the above reaction is unstable, the enthalpy cannot be determined directly in the laboratory. Use Hess’s law to determine the enthalpy of the above reaction using the information below.

2 NaCl (s) + H2O (l) ? 2 HCl (g) + Na2O (s) ? Ho = 506.89 kJ

NO (g) + NO2 (g) + Na2O (s) ? 2 NaNO2 (s) ? Ho = -427.17 kJ

NO (g) + NO2 (g) ? N2O (g) + O2 (g) ? Ho = -42.89 kJ

2 HNO2 (l) ? N2O (g) + O2 (g) + H2O (l) ? Ho = 33.07 kJ

Quote your answer to one decimal place.
