SO2Cl2 first order 600 K 2.3×10^5 s 320℃ 2.2×10^(-5) s-1

 

 

The gas-phase decomposition of SO2Cl2,

SO2Cl2(g) → SO2(g) + Cl2(g), is first order in SO2Cl2.

 

(a) At 600 K, the half-life for this process is 2.3×10^5 s.

What is the rate constant at this temperature?

 

(b) At 320℃, the rate constant is 2.2×10^(-5) s^-1.

What is the half-life at this temperature?

t_1/2 = 0.693 / k

( 참고 https://ywpop.tistory.com/26 )

 

k = 0.693 / t_1/2

= 0.693 / (2.3×10^5 s)

= 3.01×10^(-6) /s

 

 

 

t_1/2 = 0.693 / (2.2×10^(-5) /s)

= 31500 s

 

 

 

답: (a) 3.0×10^(-6) /s, (b) 3.2×10^4 s
