Question

For the reaction between carbon and oxygen to form carbon monoxide, beginning with 0.85 mol of C,

2C(s) + O2(g) → 2CO(g)

how many moles of O2 are required to completely consume the C?

how many moles of CO are obtained when the C is completely reacted?

Question:

For the reaction between carbon and oxygen to form carbon monoxide, beginning with 0.85 mol of C,

$$2C(s) + O2(g) \rightarrow 2CO(g)$$

how many moles of O2 are required to completely consume the C?

how many moles of CO are obtained when the C is completely reacted?

Solution:

As we can see on the reaction equation, amount of substance of Oxygen is equal to a half amount of Carbon, and amount of Carbon monoxide is equal to amount of Carbon.

$$N(O_2) \text{ (moles)} = 0.85/2 = 0.425$$ $$N(CO) \text{ (moles)} = 0.85$$

Answer: 0.425 moles of O₂ and 0.85 moles of CO
