Le Chatelier Principle | MCQs
کیمیائی توازن کی بہترین وضاحت ______ کے طور پر کی گئی ہے؟
A. The reaction in which concentration of reactants and products becomes the same
B. The reaction in which the rate of reverse reaction is equal to the forward reaction
C. None of these
D. The reaction in which the reverse reaction is faster than the forward reaction
Explanation
Chemical equilibrium occurs when the forward and reverse reactions occur at the same rate .
At this point, the concentrations of reactants and products remain constant, not necessarily equal.
Show/Hide Explanation
A. Le Chatelier’s Principle
B. Dalton’s Law
C. Charles’s Law
D. Boyle’s Law
Explanation
Le Chatelier's principle states that when a system at equilibrium is subjected to a change (like temperature), the system will shift to counteract the change and re-establish a new equilibrium.
