For the reaction
2A + B → 3C + D
An incorrect expression for the rate of reaction is:
The following reaction was carried out at 300 K.
The rate of formation of is related to the rate of disappearance of by the following expression:
4. None of the above.
The correct expression for the rate of reaction given below is:
For a general reaction A B, the plot of the concentration of A vs. time is given in the figure.
The slope of the curve will be:
A reaction is first-order with respect to A and second-order with respect to B. The concentration of B is increased three times. The new rate of the reaction would:
1. Decrease 9 times.
2. Increase 9 times.
3. Increase 6 times.
4. Decrease 6 times.
For the reaction,
the value of the rate of disappearance of is given as . The rate of formation of is given respectively as:
1. 6.25 x 10-3 mol L-1s-1 and 6.25 x 10-3 mol L-1s-1
2. 1.25 x 10-2 mol L-1s-1 and 3.125 x 10-3 mol L-1s-1
3. 6.25 x 10-3 mol L-1s-1 and 3.125 x 10-3 mol L-1s-1
4. 1.25 x 10-2 mol L-1s-1 and 6.25 x 10-3 mol L-1s-1
During the formation of ammonia by Haber's process N2+3H2 → 2NH3, the rate of appearance of NH3 was measured as 2.5 x 10-4 mol L-1 s-1. The rate of disappearance of H2 will be:
1. 2.5 x 10-4 mol L-1 s-1
2. 1.25 x 10-4 mol L-1 s-1
3. 3.75 x 10-4 mol L-1 s-1
4. 15.00 x 10-4 mol L-1 s-1
For the reaction, N2 + 3H2 2NH3, if=2 x 10-4 mol L-1 s-1, the value of would be:
The rate constant of a particular reaction has the dimensions of a frequency. The order of the reaction is:
1. Order is not influenced by the stoichiometric coefficient of the reactants.
2. Order of reaction is the sum of power to the concentration terms of reactants to express the rate of reaction.
3. The order of reaction is always a whole number.
4. Order can be determined by experiments only.
