An engineer examining the oxidation of so 2 in the manufacture of sulfuric acid determines that kc = 1.7 x 108 at 600 k:
2so2(g) + o2(g) ⇌ 2so3(g)
(a) at equilibrium, pso3 = 300. atm and po2 = 100. atm. calculate pso2.

Explanation:

We are given:

Relation of with is given by the formula:

Where,

= equilibrium constant in terms of partial pressure = ?

= equilibrium constant in terms of concentration

R = Gas constant =

T = temperature =

= change in number of moles of gas particles =

Putting values in above equation, we get:

The chemical reaction follows the equation:

The expression for for the given reaction follows:

We are given:

Putting values in above equation, we get:

Hence, the partial pressure of the at equilibrium is 0.017 atm.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
