Chemical Equilibrium
33465
In the thermal decomposition of potassium chlorate given as ,\(2K\,Cl{O_3}\xrightarrow{{}}2KCl + 3{O_2}\) law of mass action
1 Cannot be applied
2 Can be applied
3 Can be applied at low temperature
4 Can be applied at high temp. and pressure
Explanation:
The thermal decomposition of potassium chlorate is an irreversible reaction and hence takes place only in the forward direction. Hence, the law of mass action is not applicable in this case.
Chemical Equilibrium
33439
A reversible reaction is one which
1 Proceeds in one direction
2 Proceeds in both directions
3 Proceeds spontaneously
4 All the statements are wrong
Explanation:
(b)Reversible reaction always attains equilibrium which proceeds both sides and never go for completion.
Chemical Equilibrium
33440
Which of the following is a characteristic of a reversible reaction
1 Number of moles of reactants and products are equal
2 It can be influenced by a catalyst
3 It can never proceed to completion
4 None of the above
Explanation:
(c)In a reversible reaction some amount of the reactants remains unconverted into products.
Chemical Equilibrium
33441
The reaction \(CaC{O_3}\) \(\rightleftharpoons\) \(CaO + C{O_2}_{(g)}\) goes to completion in lime kiln because
1 Of the high temperature
2 \(CaO\) is more stable than \(CaC{O_3}\)
3 \(CaO\) is not dissociated
4 \(C{O_2}\) escapes continuously
Explanation:
(d) In lime klin \(C{O_2}\) escaping regularly so reaction proceeds in forward direction.
