A mixture of CO (g) and H2 (g) is pumped into a previously evacuated 2.0 L reaction vessel. The total pressure of the reaction system is 1.2 atm at equilibrium. What will be the total pressure of the system if the volume of the reaction vessel is reduced to 1.0 L at constant temperature? (A) Less than 1.2 atm b. Greater than 1.2 atm but less than 2.4 atm (C) 2.4 atm (D) Greater than 2.4 atm

Alayna Key · Answer 1

The answer to your question is letter C, 2.4 atm

Explanation:

Data

Volume 1 = V1 = 2 L

Pressure 1 = P1 = 1.2 atm

Pressure 2 = P2 = ?

Volume 2 = V2 = 1 L

Formula

P₁V₁ = P₂V₂

Solve for P₂

P₂ = P₁V₁ / V₂

Substitution

P₂ = (2) (1.2) / 1

Simplification

P₂ = 2.4 / 1

Result

P₂ = 2.4 atm
