Question

If a flask initially contains 1.0 atm of A and 1.2 atm of B, what is the pressure in the flask if the reaction proceeds to completion? (Assume constant volume and temperature.) If a flask initially contains 1.0 of and 1.2 of , what is the pressure in the flask if the reaction proceeds to completion? (Assume constant volume and temperature.) 3.2 atm 2.2 atm 1.7 atm 1.2 atm

Answer 1

Answer:

Explanation:

According to Dalton's partial pressure law, the total pressure of a mixture of gases is the sum of the individual pressure of the gases that make up the mixture. Mathematically;

$P_total = P_1 + P_2 + ...... + P_n$

In this case;

$P_{total} = P_A + P_B$

            1. 0 + 1.2 = 2.2 atm.

The correct answer is 2.2 atm.
