CHEMICAL KINETICS

23415 In the reaction \(2A + B \to {A_2}B\), if the concentration of \(A\) is doubled and of \(B\) is halved, then the rate of the reaction will

1 Increase by four times
2 Decrease by two times
3 Increase by two times
4 Remain the same
CHEMICAL KINETICS

23416 The term \(\left( { - \frac{{dc}}{{dt}}} \right)\) in a rate equation refers to the

1 Concentration of the reactant
2 Decrease in concentration of the reactant with time
3 Increase in concentration of the reactant with time
4 Velocity constant of the reaction
CHEMICAL KINETICS

23417 The rate of a reaction depends upon the

1 Volume
2 Force
3 Pressure
4 Concentration of reactant
CHEMICAL KINETICS

23418 For a given reaction \(3A + B \to C + D\) the rate of reaction can be represented by

1 \( - \frac{1}{3}\frac{{d[A]}}{{dt}} = \frac{{ - d[B]}}{{dt}} = \frac{{ + d[C]}}{{dt}} = \frac{{ + d[D]}}{{dt}}\)
2 \( - \frac{1}{3}\frac{{d[A]}}{{dt}} = \frac{{d[C]}}{{dt}} = K{[A]^m}{[B]^n}\)
3 \( + \frac{1}{3}\frac{{d[A]}}{{dt}} = \frac{{ - d[C]}}{{dt}} = K{[A]^n}{[B]^m}\)
