Combustion of liquid methanol

Question

Assignment:

Consider the combustion of liquid methanol,
CH₃OH(l): CH₃OH(l) + 3/2O₂(g)>> CO₂(g)+2H₂O(l)ΔH = -726.5kJ

Q1)What is the enthalpy change for the reverse reaction?
Express your answer using four significant figures.

Q2)Balance the forward reaction with whole-number coefficients: αCH₃OH(l)+βO₂(g)>>γCO₂(g)+δH₂O(l)
Give your answer as an ordered set of numbers α,β , γ, ... Use the least possible integers for the coefficients.

Q3)What is ΔH for the reaction represented by this equation?
Express your answer using four significant figures.

Q4)Which is more likely to be thermodynamically favored, the forward reaction or the reverse reaction?

Q5)If the reaction were written to produce H₂O(g) instead of H₂O(l), would you expect the magnitude of ΔH to increase, decrease, or stay the same?
