A chemical reaction is carried out in a closed container. The energy absorbed by the chemical reaction is 50 kJ. What is the energy liberated from the air or the walls of the container?
Question 10 options:
25 kJ
50 kJ
75 kJ
100 kJ
If a chemical reaction is carried out in a closed container, the law of conservation of energy states that the total energy of the system remains constant. Therefore, the energy absorbed by the chemical reaction is equal to the energy liberated from the air or the walls of the container. So, the energy liberated from the air or the walls of the container is also 50 kJ.
The correct option is:
50 kJ
