For `I^(st)` order decomposition of `SO_2Cl_2(g)`, `SO_2Cl_2(g)toSO_2(g)+Cl_2(g)` a graph of log (a-x) `v//s` t is shown in figure answer the following using above information. What is the rate constant (in `sec^(-1)`) ?A. 0.2B. `4.6xx10^(-1)`C. `7.7xx10^(-3)`D. `1.15xx10^(-2)` |

Answer» Correct Answer - C `{:(,SO_2Cl_2(g)to,SO_2(g)+,Cl_(2)(g)),(at " "t=0,a,0,0),(at " " t=t ,(a-x), x, x):}` `K=2.303/t "log" (a/(a-x))` `log (a-x)=[-K/2.303]t+log a` slope=`-K/2.303=-2/10` `K=2/10xx2.303/60sec^(-1)` `=7.7xx10^(-3) sec^(-1)` |
