Which of the following are correct for zero-order reactions?
GREYUIT [131]

Answer:

The answer is "Choice A and Choice B"

Explanation:

The Zero-Order reactions are usually found if a substrate, like a surface or even a catalyst, is penetrated also by reactants. Its success rate doesn't depend mostly on the amounts of the various reaction in this reaction.

Let the Rate = k

As \frac{dx}{dt} \ rate\ \  K_0 doesn't depend on reaction rate, a higher reaction rate does not intensify the reaction.

By the rate k_0 =\frac{dx}{dt}, the created based and the reaction rate is about the same.

An equal number of moles of KI (potassium iodide) and MgI2 (magnesium iodide) are dissolved in equal volumes of water.
SOVA2 [1]
<span>  As we know that MgI2 (magnesium iodide) when dissociated it gives more ions than  the KI so it has more boiling point as its boiling point is high it means that it boils more so it has low vapor pressure and freezing point

On the other hand as we know that KI dissociates into two  ions so so it has high freezing and vapor pressure
hope it helps</span>
