Question

In a given reaction under standard conditions in a closed container, which type of reaction would show no real increase in the rate of the reaction when the concentration of each reactant is doubled?

• A. A zero order
• B. A first order
• C. A second order
• D. A third order

Answer 1

The correct option is A A zero order

For a zero-order reaction, the rate of reaction is constant and is equal to the rate constant. i.e. Rate=K where k is rate constant.

It implies, a zero-order reaction is independent of the concentration of reactants.

Therefore, there will be no change in the rate of a zero order reaction when the concentration of each order reaction when the concentration of each reactant is doubled.
