Given Information:
- The dissociation of CO2 can be expressed as 2CO2 = 2CO + O2.
- Initially, 2 mol of CO2 is taken.
- 40% of the CO2 is dissociated completely.
To Find:
The total number of moles at equilibrium.
Explanation:
To find the total number of moles at equilibrium, we need to consider the stoichiometry of the reaction and the extent of dissociation.
1. Stoichiometry of the Reaction:
- The balanced equation for the dissociation of CO2 is 2CO2 = 2CO + O2.
- According to the stoichiometry of the reaction, for every 2 mol of CO2, we get 2 mol of CO and 1 mol of O2.
2. Extent of Dissociation:
- It is given that 40% of the CO2 is dissociated completely.
- This means that 40% of the 2 mol of CO2 dissociates completely, while the remaining 60% remains undissociated.
3. Calculation of Moles:
- 40% of 2 mol CO2 dissociates completely, resulting in 0.4 * 2 = 0.8 mol of CO and 0.4 mol of O2.
- The remaining 60% of CO2 remains undissociated, which is 0.6 * 2 = 1.2 mol of CO2.
4. Total Moles at Equilibrium:
- To find the total number of moles at equilibrium, we add the moles of each species together.
- Total moles at equilibrium = moles of CO2 + moles of CO + moles of O2
= 1.2 mol + 0.8 mol + 0.4 mol
= 2.4 mol
Answer:
The total number of moles at equilibrium is 2.4 mol. Therefore, the correct option is a) 2.4.
- The dissociation of CO2 can be expressed as 2CO2 = 2CO + O2.
- Initially, 2 mol of CO2 is taken.
- 40% of the CO2 is dissociated completely.

4. Total Moles at Equilibrium:
- To find the total number of moles at equilibrium, we add the moles of each species together.
- Total moles at equilibrium = moles of CO2 + moles of CO + moles of O2
= 1.2 mol + 0.8 mol + 0.4 mol
= 2.4 mol
Answer:
The total number of moles at equilibrium is 2.4 mol. Therefore, the correct option is a) 2.4.
