Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: pcl3(g)+cl2(g)⇌pcl5(g). a 7.5-l gas vessel is charged with a mixture of pcl3(g) and cl2(g), which is allowed to equilibrate at 450 k. at equilibrium the partial pressures of the three gases are ppcl3 = 0.125atm , pcl2 = 0.155atm , and ppcl5 = 1.90atm kp= 98.1 what is kc?

The equilibrium constant in terms of concentration that is, .

Explanation:

The relation of is given by:

= Equilibrium constant in terms of partial pressure.=98.1

= Equilibrium constant in terms of concentration  =?

T = temperature at which the equilibrium reaction is taking place.

R = universal gas constant

= Difference between gaseous moles on product side and reactant side=

The equilibrium constant in terms of concentration that is, .

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

ok whats the question if not i cannot you i need question and need a thing to answer
