Energy: Forms, Transformation, Transfer, and Conservation
Item RG212001: If the chemical energy of the products of a chemical reaction is greater than the chemcial energy of the reactants, energy was taken in from the surroundings because the amount of energy required to break bonds of the reactant molecules is greater than the amount of energy released when bonds of the product molecules are formed.
The graph below represents the amount of chemical energy in a system of reactants before a chemical reaction occurs and the amount of chemical energy in the system of products after the reaction occurs.
Is energy taken in from or released to the surroundings the surroundings during this reaction and why?
- Energy is taken in from the surroundings because the amount of energy released when bonds of the reactant molecules are broken is less than the amount of energy required to form bonds of the product molecules.
- Energy is taken in from the surroundings because the amount of energy required to break bonds of the reactant molecules is greater than the amount of energy released when bonds of the product molecules are formed.
- Energy is released to the surroundings because the amount of energy required to break bonds of the reactant molecules is less than the amount of energy released when bonds of the product molecules are formed.
- Energy is released to the surroundings because the amount of energy released when bonds of the reactant molecules are broken is greater than the amount of energy required to form bonds of the product molecules.
