Quiz 1 (Unsolved)The van der Waals constants ( a ) and ( b ) represent, respectively, the effect of molecular attractive forces (( a )) and the "own volume" of the molecules (( b)). ,An ( N_2) - He gas mixture has a total pressure of 2.0 atm and a partial pressure of ( N_2) of 0.40 atm. What is the mole fraction \( X \) of He in the mixture?,For an ideal gas, the compression factor \( Z \) can be larger or smaller than 1.,For temperatures above the critical temperature \( T_c \), there is no distinction between gas and liquid phases even at very high pressure.
Quiz 1-inclass activity (Unsolved)Hess's law proves that enthalpy change is a state function.,The combustion reaction is an exothermic process where its molar enthalpy can be measured by constant-pressure calorimeter..For all of the followings the standard molar enthalpy of formation = 0, except........,Which one is a correct thermodynamic equation of formation:(A) NH4NO3 (s) -> N2 (g) + 2H2 (g) + O3 (g) (B) N2 (g) + 2H2 (g) + O3 (g) -> NH4NO3 (s) (C) 2Na(s) + Cl2 (g) -> 2NaCl(s) (D) \( \frac{1}{2} \) N2 (g) + \( 1\2 ) H2 (g) + \( \frac{3}{2} \) O2 (g) -> HNO3 (l) (E) C(graphite) + 2H2 (g) + O (g) -> CH3OH (l),Calculate the standard molar enthalpy of formation of \( H_2O(l) \), given that: \[ H_2(g) + \frac{1}{2} O_2(g) \rightarrow H_2O(l), \quad \Delta H^\circ_{rxn} = -286 \text{kJ/mol} \]
