• A. velocity of $K^{+}$ is greater than that of $N{O}_3^{-}$
• B. velocity of $N{O}_3^{-}$ is greater than that of $K^{+}$
• C. velocity of both $K^{+}$ and $N{O}_3^{-}$ are nearly same
• D. $KN{O}_3$ is soluble in water

Answer 1

Answer: (C)

Velocity of both $K^{+}$ and $N{O}_3^{-}$ is nearly the same.
