JEE Main Chemistry question
Which of the following is not a characteristic property of chemical equilibrium? [EAMCET 2006]
- (A)Rate of forward reaction is equal to rate of backward reaction at equilibrium
- (B)After reaching the chemical equilibrium, the concentrations of reactants and products remain unchanged with time
- (C)For , is . If this reaction is carried out in the presence of a catalyst, the value of decreasesCorrect
- (D)After reaching the equilibrium, both forward and backward reactions continue to take place
Answer: (C)
Solution
A catalyst never changes the value of ; it only speeds up attainment of equilibrium. So (C) is false (not a true characteristic).
