Which changes can reach dynamic equilibrium

A - nuclear only

B - chemical only

C - nuclear and physical

D - chemical and physical

D - chemical and physical

Explanation:

Only chemical and physical changes can reach the level of dynamic equilibrium. Nuclear reactions cannot reach dynamic equilibrium.

A system is in dynamic equilibrium when the rate of forward reaction is the same as that of backward reaction in a reversible reaction. Nuclear reactions cannot be reversed. Dynamic equilibrium is prominent in chemical reactions. It is commonly found that as a reaction occurs, the backward and forward reactions can reach equilibrium levels. In physical changes, this can also occur when certain conditions of pressure and temperatures are satisfied.
