Vedclass · Answer

(C) Let the rate law be $r = k[I_2]^x [H^{+}]^y [CH_3COCH_3]^z$.Comparing experiments $2$ and $3$: When $[H^{+}]$ and $[CH_3COCH_3]$ are constant,doubling $[I_2]$ ($0.01$ to $0.02$) does not change the rate $(0.192)$. Thus,$2^x = 1 \Rightarrow x = 0$.Comparing experiments $1$ and $2$: When $[I_2]$ and $[CH_3COCH_3]$ are constant,doubling $[H^{+}]$ ($0.1$ to $0.2$) doubles the rate ($0.096$ to $0.192$). Thus,$2^y = 2 \Rightarrow y = 1$.Comparing experiments $2$ and $4$: When $[I_2]$ and $[H^{+}]$ are constant,doubling $[CH_3COCH_3]$ ($0.1$ to $0.2$) doubles the rate ($0.192$ to $0.384$). Thus,$2^z = 2 \Rightarrow z = 1$.Total order $= x + y + z = 0 + 1 + 1 = 2$.The orders are $0, 1, 1, 2$.
