A hot metal plate at 150°C has been placed in air at room temperature. Which event would most likely take place over the next few minutes? A. Molecules in both the metal and the surrounding air will start moving at lower speeds.
b. Molecules in both the metal and the surrounding air will start moving at higher speeds.
c. The air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up.
d. The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

A

Explanation:

The molecules in both metal and surrounding air will start moving slower because of the sudden decrease in environment tmeperature. The thermal energy around the metal plate decreases, also decreasing the kinetic energy.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
