The correct Answer is:
To solve the question regarding the experimental rate equation for the alkaline hydrolysis of `RBr`, we need to analyze the provided rate equation and understand the implications of the reaction mechanism. ### Step-by-Step Solution: 1. **Understanding the Rate Equation**: The given rate equation is: \[ \text{Rate} = K [RBr][\overset{\theta}{O}H] \] This indicates that the rate of the reaction depends on the concentrations of both the alkyl bromide (RBr) and hydroxide ion (OH⁻). **Hint**: Identify the components of the rate equation and their roles in the reaction. 2. **Identifying the Reaction Mechanism**: The reaction of an alkyl bromide with a base (like NaOH) to form an alcohol is typically an SN2 reaction for primary and some secondary alkyl halides. In this mechanism, the nucleophile (OH⁻) attacks the carbon atom bonded to the bromine atom, leading to the displacement of bromide ion in a single concerted step. **Hint**: Recall the characteristics of SN2 mechanisms, including the bimolecular nature and the single-step process. 3. **Determining the Order of the Reaction**: Since the rate equation shows that the rate is dependent on both [RBr] and [OH⁻], we can conclude that the reaction is second order overall (first order with respect to RBr and first order with respect to OH⁻). **Hint**: Remember that the overall order of a reaction is the sum of the powers of the concentration terms in the rate law. 4. **Evaluating the Statements**: We need to assess the provided statements regarding the reaction. The statements will likely include information about the order of the reaction, the mechanism, and the products formed. **Hint**: Compare each statement against the established facts about the reaction mechanism and rate law. 5. **Identifying the Inconsistent Statement**: Based on the analysis, we find that: - The reaction is indeed bimolecular and second order. - The reaction proceeds via an SN2 mechanism. - The statement claiming that the reaction process is false is inconsistent because the reaction does occur as described. **Hint**: Look for any statement that contradicts the established facts about the reaction mechanism or the rate law. ### Conclusion: The inconsistent statement among the options provided is that the reaction process is false. This is incorrect because the hydrolysis of RBr does occur, confirming that the only wrong statement is option C. ### Final Answer: The inconsistent statement is: **Option C - The reaction process is false.**

To solve the question regarding the experimental rate equation for the alkaline hydrolysis of `RBr`, we need to analyze the provided rate equation and understand the implications of the reaction mechanism. ### Step-by-Step Solution: 1. **Understanding the Rate Equation**: The given rate equation is: \[ \text{Rate} = K [RBr][\overset{\theta}{O}H] ...
