Question

40ml of co is exploded with 60ml of o2 at constant temperature and pressure find volume of gas in ml​

Answer 1

Answer : The volume of gas is, 40 ml

Explanation :

The balanced chemical reaction will be,

$2CO(g)+O_2(g)\rightarrow 2CO_2(g)$

First we have to calculate the limiting and excess reagent.

From the balanced chemical reaction we conclude that,

At constant temperature and pressure,

$2\times 22.4L$ of $CO$ gas react with 22.4 L of $O_2$ gas

So, 0.04 L of $CO$ gas react with $\frac{22.4L}{2\times 22.4L}\times 0.04L=0.02L$ of $O_2$ gas

That means, the $CO$ gas is a limiting reagent and $O_2$ gas is an excess reagent.

Now we have to calculate the moles volume of $CO_2$ gas.

As, $2\times 22.4L$ of $CO$ gas react to give $2\times 22.4L$ of $CO_2$ gas

So, 0.04 L of $CO$ gas react with 0.04 L of $CO_2$ gas

The volume of $CO_2$ gas = 0.04 L = 40 ml

Therefore, the volume of gas is, 40 ml
