Answer 1

The thermal decomposition of SO2Cl2at a constant volume is represented by the above equation.

After time, t, total pressure,Pt = (Pº - p) + p + p

⇒ Pt = (Pº + p)

⇒ p = Pt - Pº

therefore, Pº - p = Pº - Pt - Pº

= 2 Pº - Pt

For a first order reaction,

k = 2.303/t Log Pº / Pº - p

= 2.303/t Log Pº / 2 Pº - Pt

When t= 100 s,

k = 2.303 / 100s log 0.5 / 2x0.5 - 0.6

= 2.231 × 10 - 3s - 1

When Pt= 0.65 atm,

P0+ p= 0.65

⇒ p= 0.65 - P0

= 0.65 - 0.5

= 0.15 atm

Therefore, when the total pressure is 0.65 atm, pressure of SOCl2 is

pSOCL2 = P0 - p

= 0.5 - 0.15

= 0.35 atm

Therefore, the rate of equation, when total pressure is 0.65 atm, is given by,

Rate = k(pSOCL2)

= (2.23 × 10 - 3s - 1) (0.35 atm)

= 7.8 × 10 - 4atm s - 1
