The correct Answer is:
To determine the order of the reaction given the rate expression \( \text{Rate} = k C_A^{1/2} C_B^{-1/2} \), we can follow these steps: ### Step 1: Identify the Rate Law Expression The rate law expression is given as: \[ \text{Rate} = k C_A^{1/2} C_B^{-1/2} \] Here, \( C_A \) and \( C_B \) are the concentrations of reactants A and B, respectively. ### Step 2: Define the Order of Reaction The order of a reaction is defined as the sum of the powers of the concentration terms in the rate law expression. ### Step 3: Identify the Powers of Each Concentration From the rate law expression: - The power of \( C_A \) is \( \frac{1}{2} \). - The power of \( C_B \) is \( -\frac{1}{2} \). ### Step 4: Calculate the Total Order To find the total order, we sum the powers of the concentrations: \[ \text{Total Order} = \left( \frac{1}{2} \right) + \left( -\frac{1}{2} \right) \] Calculating this gives: \[ \text{Total Order} = \frac{1}{2} - \frac{1}{2} = 0 \] ### Step 5: Conclusion Thus, the order of the reaction is \( 0 \). ### Final Answer The order of the reaction is \( 0 \). ---
