Question

question 1
a system is in dynamic equilibrium...
when the rate of the forward process is equal to the rate of the reverse process.
when the system is changing constantly.
when the process has completely finished.
when the amounts on both side of a system are equal.

Explanation:

To determine the correct option for dynamic equilibrium, recall the definition: Dynamic equilibrium occurs in reversible processes when the rate of the forward reaction (or process) equals the rate of the reverse reaction (or process). Let's analyze each option:

• First option: Matches the definition of dynamic equilibrium (forward and reverse rates are equal).
• Second option: A system in constant, unbalanced change is not in equilibrium.
• Third option: A finished process (no ongoing reactions) is static, not dynamic equilibrium.
• Fourth option: Dynamic equilibrium does not require equal amounts (concentrations/quantities) on both sides, just equal rates.

Answer:

A. when the rate of the forward process is equal to the rate of the reverse process.
