Thermochemical equation

[Cristian Carrasco 1F]

Can someone explain what a thermochemical equation is ?

[sofiakavanaugh]

I think a thermochemical equation is just a chemical equation that includes the change in enthalpy for the reaction (delta H)

A thermochemical equation is a balanced chemical equation that has the physical states of all reactants and products along with the energy change. The reaction is endothermic if energy is a reactant and exothermic if energy is a product.

[Peter Dis1G]

A Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH. In variable form, a thermochemical equation would look like this: A + B → C. ΔH = (±) #

Can someone explain why the thermochemical equation on pg 288 example 8.7 is that change in enthaply= q x (2 mol)/n? Why would you divide the stoichiometric coefficient of original equation by the number of mols?

[Sara Sasaki 1K]

I believe it is because there are 2 moles of C6H6, and so in order to find the change in enthalpy you must multiply by 2. I think the book explains this a little more at the top of page 289 if that helps!
