Which statement best describes the reaction pathway graph for endothermic reactions? mainly downhill always linear always parabolic mainly uphill

I think the correct answer would be always parabolic. The reaction pathway graph for an endothermic reaction would always be parabolic where the products have higher energy than the reactants. Hope this answers the question.

Endothermic reaction is a type of reaction that absorbs energy during the process. the gauge for this reaction is the change in enthalpy which should be positive. This means the energy of the products should be greater than the energy of the reactants. The graph illustrates an uphill form. 

answer: mole of the gas

answer: mole of the gasexplanation:

answer: mole of the gasexplanation: this is because 1 mole of a gas is 22.4dm³, which is use in ideal gas
