Determine the standard enthalpy of formation of methane (CH4) using Hess's Law, given the following reactions and enthalpy changes: 1. C(graphite) + 2H2(g) -> CH4(g) ΔH1 = -74.6 kJ/mol 2. 2H2(g) + O2(g) -> 2H2O(l) ΔH2 = -571.7 kJ/mol 3. C(graphite) + O2(g) -> CO2(g) ΔH3 = -393.5 kJ/mol.

Consider the reaction: 2NOBr(g) ⇌ 2NO(g) + Br2(g)The Kc value for this reaction at a certain temperature is 0.045. A catalyst is added to the reaction mixture that increases the rate of the forward and reverse reactions to the same extent. What effect will this catalyst have on the equilibrium position of the reaction mixture? Justify your answer using calculations.
