Determine the standard enthalpy of formation for hydrogen chloride gas using the following data:H2(g) + Cl2(g) → 2HCl(g) ΔH = -184.6 kJ/molH2(g) + 1/2O2(g) → H2O(l) ΔH = -285.8 kJ/mol2HCl(g) + O2(g) → 2ClO(g) + H2O(l) ΔH = -518.2 kJ/mol Note: The standard enthalpy of formation for a compound is the change in enthalpy that occurs when one mole of the compound is formed from its constituent elements, with all substances in their standard state at a given temperature (usually 25°C) and pressure (usually 1 atm).

Consider the following equilibrium reaction:2NO(g) + Br2(g) ⇌ 2NOBr(g)If the initial concentration of NO is 0.10 M, Br2 is 0.20 M, and NOBr is 0.40 M, what would be the concentration of NOBr when additional Br2 is added such that its concentration is doubled? Calculate the new equilibrium concentration of NOBr assuming all other conditions remain the same.
