Answer:

See explanation

Explanation:

Solvolysis is a chemical reaction in which the solvent, such as water or alcohol, is one of the reagents and is present in great excess of that required for the reaction. The solvents act as or produce electron-rich atoms or groups of atoms (nucleophiles) that displace an atom or group in the substrate molecule(Encyclopedia Britannica).

For the two reactions, the organic product is the same(the product is drawn in the second image attached). The both reactions occur by SN1 mechanism since the substrate is a tertiary alkyl halide. The nucleophile is CH3OH and the rate of reaction depends on the concentration of the alkyl halide and independent of the concentration of methanol present.

Therefore, changing the volume of the solvent has no effect on the rate of reaction. The two reactions proceed at exactly the same rate since the initial concentration of the alkyl halide is the same for both reactions.
