Really dont understand this question The equilibrium constant Kp for the gas phase thermaldecomposition of tert-butyl chloride is 3.45 at 500 K: (CH3)3CCL(g)yield (CH3)2=CH2 (g) +HCl (g) (a) calculate the value of Kc at 500 K (b) calculate the molar concentrations of reactants andproducts in an equilibrium mixture obtained by heating 1.00 mol oftert-butyl chloride in a 5.00L vessel at 500 K.

There's a small mistake in the species yeild it should be(CH3)2C=CH2. (a) Kp = Kc RT^n 3.45 = Kc (.0821 x500)1 (n = 2-1=1) Kc = 3.45/41.05 =0.084 moles/ltr. (b) (CH3)3CCl ----------------->(CH3)2C=CH2 + HCl initial conc. 1 0 0 At EQ. 1- no. of moles 1- /V /V /V Kc= (/V)2/[(1-)/V] neglecting 1-,,,,,,,,,,,,,,,,,,,,,,, Kc = 2 /V 2 = 0.42 = 0.648 eq concen. of reactant = 1- =0.352 eq concen. of product = =0.642.
