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 is zero and in the second case, net external torque appli...
Overall, dynamic equilibrium is a steady state reached when a reversible reaction occurs at the same rate in both directions and has an unchanging ratio of products and reactants. The equilibrium constant, K, of a reaction is the ratio of product to reactant concentrations, as defined by the...
