- Identify trends in S values: (a) For the halogens: F2(g), Cl2(g), Br2(), I2(s). (b) For the gaseous hydrocarbons: CH4, C2H6, C3H8.arrow_forwardGiven the following data calculate H for the reaction On the basis of the enthalpy change, is this a useful reaction for the synthesis of ammonia?arrow_forwardThe steps of the Born-Haber cycle are shown for the ionic compound MX2, made up of generic metal M and generic, gaseous halogen X. Identify the overall reaction and identify the name of the enthalpy change for each reaction.arrow_forward
- he combustion of hydrogen gas releases 286 kJ per mol of hydrogen. If 11.0 L of hydrogen at STP was burned to produce electricity, how long would it power a 100-watt (W) light bulb? Assume no energy is lost to the surroundings. (1 W = 1 J/s)arrow_forwardFrom these data, calculate the value of ΔH° for the reaction.arrow_forwardDulong and Petit’s law states that specific heat capacity x atomic mass = 3R. If the specific heat capacity of an element is 0.93 J/goC, identify the element.arrow_forward
- The following sequence of reactions occurs in the commercial production of aqueous nitric acid:4NH3(g) + 5O2(g) ⟶ 4NO(g) + 6H2 O(l) ΔH = −907 kJ2NO(g) + O2(g) ⟶ 2NO2(g) ΔH = −113 kJ3NO2 + H2 O(l) ⟶ 2HNO3(aq) + NO(g) ΔH = −139 kJ Determine the total energy change for the production of one mole of aqueous nitric acid by this process.arrow_forwardThe chemistry of nitrogen oxides is very versatile. Given the following reactions and their standard enthalpy changes, (1) NO(g) + NO2(g) → N2O3(g) ΔH o/rxn= −39.8 kJ (2) NO(g) + NO2(g) + O2(g) →N2O5(g) ΔH o/rxn = −112.5 kJ (3) 2NO2(g) → N2O4(g) ΔH o/rxn = −57.2 kJ (4) 2NO(g) + O2(g) → 2NO2(g) ΔH o/rxn = −114.2 kJ (5) N2O5(s) →N2O5(g) ΔH o/rxn = 54.1 kJ Calculate the heat of reaction for N2O3(g) + N2O5(s) →2N2O4(g) ΔH= ? kJarrow_forwardThe combustion of hydrogen gas releases 286kJ per mol of hydrogen. If 11.0 L of hydrogen at STP was burned to produce electricity, how long would it power a 100-watt (W) light bulb? Assume no energy is lost to the surroundings. (1W = 1 J/s)arrow_forward
