The rate of a reaction can be increased in general by all the factors except by

The concentration of reactant changes from 0.06 mol L^-1 to 0.05 mol L^-1 in 25 minutes. Calculate the average rate of reaction.

5A→ 2B

If there were 1.5 moles of 'A' 2 L solution in the beginning of the reaction, what is the concentration of 'B' when 'A' is 20% consumed?

The rate constants were found to be K₁ and K₂, when a reaction was carried out at 310 K and 290 K respectively.

The two rate constants are related as:

The following reaction takes place in one step:

\(2 \mathrm{NO}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{~g}) \leftrightharpoons 2 \mathrm{NO}_{2}(\mathrm{~g})\)

How will the rate of the above reaction change if the volume of the reaction vessel is diminished to one-third of its original volume?
