Matter Project: Calculating the Enthalpy of Reaction From Bond Energies

For advanced chemists, this worksheet examines heat change during chemcial reactions. Alkanes are examined first. Learners calculate the energy released or needed during a reaction.

Before completing this instructional activity, chemists are supposed read a portion of their textbook. Assign the chapter on bond energies, endothermic, and exothermic reactions. Then have your class answer the questions and fill in the...

Explanation of bond enthalpy that includes examples of calculating enthalpies of reaction using bond enthalpy.

Have you reached your breaking point in looking for great resources that illustrate bond energy? Demonstrate the potential energy changes that occur when polar and non-polar bonds are broken with a stimulating simulation. Pupils pull on...

An explanation of using bond enthalpy to calculate enthalpy of reaction. [11:47]

Explain the complex concept of bond energies through a comprehensive video lesson. The final lesson in a 35-part series defines bond enthalpy and then leads scholars through several calculations. Each example increases in complexity,...

In this thermodynamics worksheet, students calculate the change in enthalpy for several given chemical equations provided. Students specify if the reaction was endothermic or exothermic in nature.

Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is also reversed....

In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond...

Mr. Mole and Mr. Matchmaker entertain and educate your chemists about how quickly or slowly reactants are used up in a chemical reaction. Thorough explanations of the influencing factors are offered, and demonstrations are done. After...
