Transcribed image text: A chemical reaction is endothermic and has an activation energy that is twice the value of the enthalpy of the reaction. Identify a diagram depicting the energy of t progresses. WebThe enthalpy of solution (ΔH soln) is the heat released or absorbed when a specified amount of a solute dissolves in a certain quantity of solvent at constant pressure. Key Takeaway Enthalpy is a state function whose change indicates the amount of heat transferred from a system to its surroundings or vice versa, at constant pressure.
