Which of the following happens when a reaction reaches dynamic equilibrium in a closed system? Reaction stops
Reaction happens in both directions,
The concentrations of the reactants and products increase.
The concentrations of the reactants and products decrease.

Reaction happens in both directions..

Explanation:

This is dynamic equilibrium, where the reactants and products are converted into each other at the same rate. If the system is closed and the temperature is held constant, the chemical reaction will achieve dynamic equilibrium.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
