• # question_answer Using the data given below the order and rate constant for the reaction: $C{{H}_{3}}CHO\left( g \right)\to C{{H}_{4}}\left( g \right)+Co\left( g \right)$ would be-      Experiment no. Initial cone. Initial rate $\left[ mol/\ell \right]$ $\left[ mol.li{{t}^{-1}}\,{{\sec }^{1}} \right]$ I 0.10 0.020 II 0.20 0.080 III 0.30 0.180 IV 0.40 0.320 Answer is- A) $2,\,\,[k=2.0\,\ell /mol\,\,sec]$B) $0,\,\,[k=2.0\,mol/\ell \,sec]$C) $\,2,\,\,[k=1.5/\ell mol\,\,sec]$D) $\,1,\,\,[k=1.5\,se{{c}^{-1}}]$

$r=K\,{{[C{{H}_{3}}CHO]}^{m}}$ $\frac{1}{4}=\,\,{{\left( \frac{1}{2} \right)}^{m}}\,\,\,\,\,\,m\,\,=\,\,2$
