When determining reaction orders by experiment, the most common procedure is to ______. Multiple choice question. keep all react
ant concentrations constant for each determination change all reaction concentrations by the same amount each time change the concentration of one reactant while keeping the other concentrations constant
change the concentration of one reactant while keeping the other concentrations constant
Explanation:
For a given reaction;
A + B --> C + D
The reaction rate may be given as;
Rate = k[A][B]
In the above rate equation, the orders of both reactants ( A and B) is 1 . Reaction order is basically how the concentration of the reactant affect the rate of the equation.
The correct option is;
change the concentration of one reactant while keeping the other concentrations constant.
That way, one can monitor how a particular reactant affect the rate of the reaction.
