Interpretation: True statement for equilibrium needs to be selected.
Concept Introduction: In a static equilibrium, reaction stops on attaining equilibrium whereas in dynamic equilibrium it doesn’t stop after attaining equilibrium. If a chemical equilibrium is static, it means that no forward or backward reaction is taking place and if it is dynamic it means that forward or backward reaction or both are taking place.
Answer to Problem 1STP
Correct answer: It is microscopically dynamic and macroscopically static.
Explanation of Solution
Reason for correct option: For a chemical equilibrium,
Reasons for incorrect options: Since the reaction is taking place at the microscopic level, it cannot be static at microscopic level. Also at the macroscopic level, reaction seems to have stopped. So it cannot be said to be dynamic at macroscopic level.
