Which changes can reach dynamic equilibrium
soldier1979 [14.2K]

Answer:

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.
