Question

What is the total volume of gases produced when 3.0 L of nitrogen trichloride (NCI3) decomposes into chlorine and nitrogen at a constant pressure and temperature?

2NC13(g) N₂(g) + 3Cl₂(g)

4.0 L
6.0 L
8.0 L
3.0 L

Answer 1

At constant pressure and temperature, 3.0 L of nitrogen trichloride decomposes to produce 4.0 L of gases; option A.

What is the moles ratio of the decomposition of the reaction?

The mole ratio of the reaction is detained from the equation of the reaction.

The equation of the reaction is given below as follows:

• 2NC13(g) ----> N₂(g) + 3Cl₂(g)

2 moles of nitrogen trichloride decomposes to produce 4 moles of gases.

The mole ratio of a gas is equivalent to the volume ratio of the gas.

Therefore, 3.0 L of nitrogen trichloride decomposes to produce 4.0 L of gases.
