NEET Chemistry Ionic Equilibrium MCQ Question
Which of the following statements about chemical equilibrium and Le Chatelier's Principle is correct?
The equilibrium constant Kc varies with changes in temperature, but is unaffected by changes in concentration or pressure.
Increasing the concentration of reactants always favors the formation of products, regardless of the reaction type.
Le Chatelier's Principle states that a system at equilibrium will shift in the direction that minimizes the energy expenditure only when temperature changes.
The value of Kp can be calculated using concentrations expressed in pascals, as long as the pressure is in standard state.
Correct Answer
Detailed Explanation
According to the NCERT context, the equilibrium constant Kc is indeed independent of initial concentrations but varies with temperature. Therefore, option A is correct.
