In a reaction of the type A+B ⇒ C+D one could ensure it to be a first order reaction by :
-
- Increasing the temperature
- Increasing the concentration of a product
- Increasing the concentration of a reactant
- Adding a catalyst
- Increasing the temperature
Correct Option: C
A first-order reaction is a reaction that proceeds at a rate that depends linearly on only one reactant concentration. In other words, when the reaction rate depends on the first power of concentration of a single reactant,’ it is considered to be first order. The rate of reaction is directly proportional to the concentration of reacting substance. Absorption, distribution, elimination rates are examples of such reaction. The following graph represents concentration of reactants versus time for a first-order reaction: Concentration Time
