Applying Stoichiometry to Heats of Reaction

EXERCISE 6.4 a. Write the theimochemical equation for the reaction described in Exercise 6.3 for the case involving 1 mol N2H4. b. Write the thermochemical equation for the reverse of the reaction described in Exercise 6.3. 

Natural gas consists primarily of methane, CH4. It is used in a process called steam reforming to prepare a gaseous mixture of carbon monoxide and hydrogen for indnstrial nse. 

The reverse reaction, the reaction of carbon monoxide and hydrogen, has been explored as a way to prepare methane (synthetic natural gas). Which of the following are exothermic Of these, which one is the most exothermic  

If you wanted the result in kilocalories, you could convert this answer as follows  

As you might expect, the quantity of heat obtained from a reaction will depend on the amount of reactants. We can extend the method used to solve stoichiometry problems, described in Chapter 3, to problems involving the quantity of heat.
