In a gaseous system at equilibrium with its surroundings, as molecules of A(g) collide with molecules of B(g) without reacting, the total energy of the gaseious system

Question

1. decreases
2. increases
3. remains the same

Answer 1

In the real world, energy will be lost to the surroundings and the energy of the system will decrease. In a theoretical world, we assume collisions with other molecules and the walls of the container are completely elastic (no loss of energy); therefore, the system's energy will ........

Answer 2

Stays the same
