Why not show your work for the ICE table and let us see what you need to do. Otherwise we're just guessing what you've done.
It appears that you need Kc = (C)/(A)(B)^2 (Note: you don't have the squared term)
Then you have x, and I assume the rest of ICE table. If you did it right, A will be 0.675-x and B will be 0.973-2x and you have x. Plug those into Kc expression and solve, then Kp=Kc(RT)^delta n where delta n is 1-3 = -2.
A United Nations toxicologist studying the properties of mustard gas, S(CH2CH2Cl)2, a blistering agent used in warfare, prepares a mixture of 0.675 M SCl2 and 0.973 M C2H4 and allows it to react at room temperature (20.0°C ).
SCl2 (g) + 2 C2H4 (g) --> S(CH2CH2Cl)2 (g)
At equilibrium, [S(CH2CH2Cl)2] = 0.350 M. Calculate Kp.
I have worked this problem out a few times and what I have done so far is use an ice table. Found x = 0.350 M. Used the equation Kp = (C)/(A)(B). Can someone please help me figure out what I need to do right!
