Which of the following statementsw about the order of a reaction is correct ?A. A second order reaction is also bimolecularB. The order of a reaction can only be determined by experimentC. We can determine the order of a reaction from the correctly balnced net ionicv equation for the reactionD. The order of a reaction must be a positive integer |
Answer» Correct Answer - B The reaction order with respect to a given reactant species equals the exponent of the concentration of that species in the rate law, as determined experimentally. Although reaction orders frequently have whole number value (particularly `1` or `2`), they can be fractional and zero also possible. A second order reaction is bimolecular reaction if and only if it is an elementry reaction. Similary, wecan determine the order of a reaction from the correctly balanced net ionic equation for the reaction provided the reaction is elementary in nature. |
