Options
- A. H _ 2( ~g ) + I _ 2( ~g ) 2 HI _ ( g )
- B. CO _ ( g ) + H _2 O _ ( g ) CO _ 2( ~g ) + H _ 2( ~g )
- C. 2 BrCl _ ( g ) Br _ 2( ~g ) + Cl _ 2( ~g )
- D. PCl _ 5( ~g ) PCl _ 3( ~g ) + Cl _ 2( ~g )
Answer
D. PCl _ 5( ~g ) PCl _ 3( ~g ) + Cl _ 2( ~g )
Step-by-step solution
aligned & K _ p = K _ c ( RT )^ n _ g \\ & for K _ p K _ c \\ & n _ g 0 \\ & n _ g = n _ p - n _ r aligned (1) n _ g =2-2=0 (2) ng _ g =2-2=0 (3) ng _ g =2-2=0 (4) ng _ g =2-1=1
