Chapter 7, Problem 88E

Interpretation Introduction

Interpretation: Standard enthalpy of combustion of liquid methanol per gram has to calculate and compare this answer to ethanol.

Concept introduction

Standard enthalpy of combustion ( ${\text{ΔH}}^{\text{0}}$): Standard enthalpy change of combustion of the substance is change in enthalpy that occurs when one mole of substance burns completely in oxygen under standard conditions.

Standard conditions: ${\text{25}}^{\text{0}}\text{C}$ and 1 atmosphere pressure.
