In an exothermic reaction, the potential energy of the products is lower than that of the reactants. Which of the following is a
lso true for an exothermic reaction?
the enthalpy change is negative
it requires a catalyst to take place
energy is absorbed from the surroundings
the kinetic energy of the products is also lower
the enthalpy change is negative
it requires a catalyst to take place
energy is absorbed from the surroundings
the kinetic energy of the products is also lower
2 answers:
Answer: the enthalpy change is negative
Explanation:
Endothermic reactions are defined as the reactions in which potential energy of the product is greater than the potential energy of the reactants. The total energy is absorbed in the form of heat and for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which potential energy of the product is lesser than the potential energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
