23411 In a reaction \(2A + B \to {A_2}B\), the reactant \( A \) will disappear at

1 Half the rate that \(B\) will decrease
2 The same rate that \( B\)  will decrease
3 Twice the rate that \(B\) will decrease
4 The same rate that \({A_2}B\) will form
CHEMICAL KINETICS

23412 The rate of a gaseous reaction is given by the expression \(K\,[A]\,[B]\). If the volume of the reaction vessel is suddenly reduced to \(1/4^{th} \) of the initial volume, the reaction rate relating to original rate will be

1 \(1\over10\)
2 \(1\over8\)
3 \(8\)
4 \(16\)
CHEMICAL KINETICS

23413 A catalyst increases the rate of reaction because it

1 Increases the activation energy
2 Decreases the energy barrier for reaction
3 Decreases the collision diameter
4 Increases the temperature coefficient

23414 For the reaction \({N_2}(g) + 3{H_2}(g) \to 2N{H_3}(g)\) under certain conditions of temperature and partial pressure of the reactants, the rate of formation of \(N{H_3}\) is \(0.001\,kg\,{h^{ - 1}}\). The rate of conversion of \({H_2}\) under the same conditions is

1 \(1.82\, \times {10^{ - 4}}\,kg/hr\)
2 \(0.0015\,kg/hr\)
3 \(1.52 \times {10^4}kg/hr\)
4 \(1.82 \times {10^{ - 14}}kg/hr\)
