You start with an equimolar mixture of the gases so₂ and o₂ in a container. the so₂ and o₂ react to completion to form so₃. if the temperature after the reaction is 25°c and the pressure in the container is 1.65 atm, what is the density of the product gas mixture? assume ideal behavior.

The density of the product gas mixture is 5.39 g/L

Explanation:

Given:

Temperature after the reaction = C

Pressure in the container = 1.65 atm

The ideal gas equation PV = nRT

To find: Density of the product gas mixture

Step 1:

Molarity (M) = P/(RT)

M = 0.0674 mol/L

Step 2:

The product of the given reaction is . Its molar mass is

1S x 32.066 g/mol = 32.066 g/mol

3O x 16 g/mol = 48 g/mol

Adding both we get 80.066 g/mol

Therefore the density of the product gas mixture is

= 5.39 g/L

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
