Question

During a certain chemical reaction, energy was transformed from the reaction system to its surroundings through molecular collisions. Which statement is true in this situation? A. the particles differed in potential energy instead of kinetic energy. B. The kinetic energy of the particles in the system and its surroundings stayed the same. C. The particles in the reaction system lost some kinetic energy. D. The particles in the surroundins lost some kinetic energy.

Answer 1

D

Step-by-step explanation:

D. The particles in the surroundings lost some kinetic energy.

When energy is transferred from the reaction system to the surroundings, it is often in the form of heat, which is a transfer of thermal energy due to random collisions between particles. This means that the particles in the surroundings gain kinetic energy, while the particles in the reaction system lose some of their kinetic energy.
