Heat Released Calculator

The Heat Released Calculator is a tool used to calculate the amount of heat energy released during a chemical reaction. The formula for calculating heat released depends on the specific reaction and the enthalpy change associated with it.

Formula

The general formula is:

Heat Released = (Mass of Reactant) × (Specific Heat Capacity) × (Temperature Change)

Example

Let’s consider the combustion of 1 mole of methane (CH4). The balanced equation is:

CH4 + 2O2 -> CO2 + 2H2O

Assuming complete combustion, the enthalpy change for this reaction is -890.3 kJ/mol. If we have 1 mole of methane and the temperature change is 100°C, we can calculate the heat released as:

Heat Released = (1 mol) × (-890.3 kJ/mol) × (100°C) = -89,030 kJ
