Le Chatelier's Principle for Del N Lesser Than Zero

Q.

Solids $CaC{O}_3$ and CaO and gaseous $C{O}_2$ are placed in a vessel and allowed to reach equilibrium

$CaO\left(s\right)+C{O}_2\left(g\right)\rightleftharpoons CaC{O}_3\left(s\right)\Delta H=-180kJmo{l}^{-1}$

The quantity of CaO in the vessel could be increased by:

1. Lowering the temperature

2. Reducing the volume of the vessel

3. Adding more of

4. Removing some of

Q.

In the reaction A(g) + 2B(g) $\rightleftharpoons$ C(g) + Q kJ of heat, more product will be obtained

or the forward reaction is favoured by

1. At high temperature and high pressure

2. At high temperature and low pressure

3. At low temperature and high pressure

4. At low temperature and low pressure

Q.

For the reaction $CaC{O}_3$(s) $\leftrightharpoons$ $CaO$(s) + $C{O}_2$(g) the partial pressure of $C{O}_2$ (at equilibrium) depends on:

1. the mass of $CaO$

2. the mass of $CaC{O}_3$

3. temperature

4. Both a and b
