Chemical Equilibrium Lesson Summary Frequently Asked Questions What is dynamic equilibrium in the body? A body is said to be in dynamic equilibrium if the body moves with a constant linear velocity or rotates with a constant angular velocity. In the first case, net external force on the body...
The equilibrium constant, K, of a reaction is the ratio of product to reactant concentrations, as defined by the balanced chemical equation. Using the equilibrium constant expression, K can be calculated or used to determine equilibrium concentrations. If only the morning traffic could equilibrate ...
