Question

Which of these statements is true about endothermic reactions, but not about exothermic reactions? (2 points) The reactants and products are different substances. The reactants have less energy than the products. The temperature of the container increases. No change in energy occurs.

Answer 1

it is b The reactants have less energy than the products.

Answer 2

Answer: The reactants have less energy than the products.

Step-by-step explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and
`\Delta H` for the reaction comes out to be positive.The temperature of the container decreases.

Exoothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and
`\Delta H` for the reaction comes out to be negative.The temperature of the container increases.

Thus for endothermic reactions, the reactants have less energy than the products.
