Can someone please explain how to find the amount of energy released in a chemical reaction? What formulas do I use and how do I use them?
1 Answer
More information is required as there are a few different ways. I am guessing you are looking at either
1) measuring by experiment using calorimetry
2) calculating using bond energies
3) calculating using standard heats of formation
Based on your comment, it looks like bond energies. In this case, the heat released (or the enthalpy of reaction
A couple of things you should know
- breaking bonds requires energy (endothermic) and making bonds releases energy (exothermic) : if the
- you need a table of bond energy (enthalpy) values to solve problems
- you need to be able to determine bonding in molecules to solve problems
Example
Reactants contain TWO
ONE
Products contain FOUR
