What is the total pressure exerted by the mixture of gases only products or products + reactants?

Cis the answer ur welcome if i get it wrong u don't have to me

Olá. porque a reação na temperatura é muito rapida a do copo : )

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

The independent is what is changed, the dependent is was is measured or the reaction.
