SO2Cl2(g) → SO2(g) + Cl2(g) 600 K rate 2.8×10^(-3) min-1

SO2Cl2(g) → SO2(g) + Cl2(g) 600 K rate 2.8×10^(-3) min-1

 

 

The decomposition of SO2Cl2

is a first-order reaction:

SO2Cl2(g) → SO2(g) + Cl2(g)

The rate constant for the reaction

is 2.8×10^(-3) min^-1 at 600 K.

If the initial concentration of SO2Cl2

is 1.24×10^(-3) mol/L,

how long will it take for the concentration

to drop to 0.31×10^(-3) mol/L?

ln(C_t / C_0) = –k•t

( 참고 https://ywpop.tistory.com/26 )

 

 

 

t = –ln(C_t / C_0) / k

= –ln(0.31 / 1.24) / (2.8×10^(-3))

= 495.1 min

 

 

 

답: 5.0×10^2 min
