The rate law for the reaction $A + B \to C$ at $2 5^{\circ} C$ is given by rate $= k [A] [B]^{2}$ . Calculate the rate of reaction if rate constant at same temperature is $6.25 mol^{- 2} dm^{6} s^{- 1} [[A] = 1 M, [B] = 0.2 M]$

Options:

Answer:

Solution:

$Rate = k [A] [B]^{2} = 6.25 mol^{- 2} dm^{6} s^{- 1} \times 1 mol dm^{- 3} \times 0.2 mol dm^{- 3} \times 0.2 mol dm^{- 3} = 0.25 mol dm^{- 3} s^{- 1}$
