In this lesson, we will learn how to calculate reaction enthalpies by comparing the standard enthalpies of formation of the reactants and the products.
Q1:
Using the data below, calculate to 3 significant figures the standard molar enthalpy of combustion of diborane (BH)26.
Q2:
Using the data in the table, calculate, to the nearest kilojoules per mole, the standard enthalpy of combustion of hydrazine (NH)24. One of the products of the reaction is nitrogen.
Q3:
Using the data in the table, calculate, to the nearest kilojoules per mole, the standard enthalpy of combustion of methane.
