Summary:
- Hess’s law allows us to indirectly calculate the heat of reaction for any reaction that occurs at standard conditions.
- An enthalpy change that occurs specifically under standard conditions is called the standard ent Halpy (or heat) of reaction and is given the symbol.
- The standard heat of.
- reaction can be calculated by using the following equation.
- The symbol “” signifies that each heat of formation must first be multiplied by its coefficient in the balanced equation.
- Calculate the standard heat.
- of reaction for the reaction of nitrogen monoxide gas with oxygen to form nitrogen.
- dioxide gas.
