Explanation / Answer

Since volume is 1 L, concentration will be same as number of moles

Qc = [CO][Cl2]/[COCl2]

= (4.92*10^-2)*(4.32*10^-2)/(0.123)

= 0.0173

Kc is 0.0129

Since Qc is greater than Kc, reaction must move in backward direction

1)

True since reaction moves in backward direction

2)

False since Kc is constant

3)

False since reaction moves in backward direction

4)

True as proved above

5)

False since Since Qc is greater than Kc
