An exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction. In an exothermic reaction, change in enthalpy ( ΔH) will be negative.

If heat is given off, it is called an exothermic reaction. If heat is absorbed, it is called endothermic reaction. In this chapter we will learn how to calculate the enthalpy change (heat change) when methane (a gas) is formed using carbon graphite and hydrogen. Hess's law. Hess's law is used to determine the enthalpy change.

Use the formula ∆H = m x s x ∆T to solve. Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve. How do you draw a reaction energy diagram?
