Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

The correct answer is Option (4) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

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)
