Which energy transformation occurs in an endothermic reaction?

Energy from the surroundings is stored in the chemical bonds of the products.

Energy from the chemical bonds of the reactants is released to the surroundings.

There is a net flow of energy from the surroundings into the system.

There is a net flow of energy from the system out to the surroundings.

Respuesta :

Energy from the surroundings is stored in the chemical bonds of the products.

  • There are 2 types of thermal chemical reactions
  1. Exothermic
  2. Endothermic

Answer:

Energy from the surroundings is stored in the chemical bonds of the products.

Explanation:

• In an endothermic reaction, the enthalpy in heat is positive. This is because energy stored in products is greater than energy remaining in reactant bonds.
