Answer is: 22,65 gramsof methanol <span>must be burned.
</span>Chemical reaction: CH₃OH + 3/2O₂ → CO₂ + 2H₂O. ΔH = -764 kJ.
Make proportion, if one mole of ethanol release 764 kJ of heat, than:
1 mol : 764 kJ = n(CH₃OH) : 541 kJ.
n(CH₃OH) = 0,708 mol.
m(CH₃OH) = n(CH₃OH) · M(CH₃OH).
m(CH₃OH) = 0,708 mol · 32 g/mol.
m(CH₃OH) = 22,65 g.
The scenario that involves a reaction that is an equilibrium would be A. The chemical reaction is producing reactants and products at an equal rate.
Your answer is going to be A, because it was shoved harder, it will go faster
Answer:
for the process is -375 kJ
