Question

which of the following will react at the highest rate?
(1) 1 mol of A and 1 mol of B in a 1 L vessel
(2) 2 mol of A and 2 mol of B in a 2 L vessel
(3) 3 mol of A and 3 mol of B in a 3 L vessel
(4) all would react at the same rate.
please explain the solution.

Answer 1

When talking about the rate of a given reaction, what we mean is that we are determining the speed at which a given chemical reaction proceed. It is normally expressed in terms of the concentration of products formed per unit time or concentration of reactants per unit time.

For a given amount of a substance to react to form a product, the rate of interaction between the molecules must be fast and maximum interaction must be achieved.

so in my view, reaction 1 will be fast since the volume where the molecules are found is small allowing them to have maximum interaction hence product formation.

Answer 2

Answer:

Explanation:

Conc= number of moles/vol(in litre)

Therefore all of the above will have the same rate.

So, 4) is correct.
