Expression (A): $r = k[A]^{0.2}[B]^{0.3}[C]$
- The exponent for $[C]$ is understood to be $1$.
- Overall Order $= 0.2 + 0.3 + 1 = 1.5$ or $3/2$.
- Match: (A) - (III)
Expression (B): $r = k[A]^{0.2}[B]^{-0.3}[C]$
- Overall Order $= 0.2 + (-0.3) + 1 = 0.9$ or $9/10$.
- Match: (B) - (IV)
Expression (C): $r = k[A][B]^{0.3}[C]^{-1}$
- The exponent for $[A]$ is $1$.
- Overall Order $= 1 + 0.3 + (-1) = 0.3$ or $3/10$.
- Match: (C) - (I)
Expression (D): $r = k[A]^{0.2}[B]^{0.3}[C]^{0.5}$
- Overall Order $= 0.2 + 0.3 + 0.5 = 1.0$ or $1$.
- Match: (D) - (II)
