Need help with #3.b and #4 please
3. You are given the following standard enthalpies of formation at 25°C HF (aq OH (aq) F (aq) H20 (1) -320.1 kJ/mol -229.6 kJ/mol -329.1 kJ/mol -285.8 kJ/mol a. Calculate the standard enthalpy of neutralization of HF (aq) HF (aq) + OH. (aq) â F (aq) + H2O (1) b. Using the value of -56.2 kJ/mol as the standard enthalpy change for the reaction H+ (aq) + OH. (aq) H2O ( 1 ) â calculate the standard enthalpy change for the reaction HF (aq) H' (aq) F (aq) -ä¸â 4. You are given the following information. =-4.8 kJ dH ÎH = 29.1 kJ N:04 (g) N2 (g) + 202 (g) 2NO2 (g) â N204 (g) â determine the enthalpy change ( ) for the reaction: N2(g) + 202 (g) 2 NO2(g)
