Question

Find temperature (in Kelvin) at which rate constant are equal for the following reaction? 
\(\text{A $\rightarrow$ B, K = 10$^4$ e$^{-24000/T}$} \)
\(\text{P $\rightarrow$ Q, K = 10$^6$ e$^{-30000/T}$} \)

Hint:

When comparing rate constants for reactions at different temperatures, use the Arrhenius equation to solve for the temperature where the rate constants become equal.

Answer 1

Correct Answer: 1303

Analysis: - **Statement I:** Henry's Law constant (\(K_H\)) is a characteristic constant for a specific gas-solvent pair at a constant temperature. It does not depend on the concentration (mole fraction) of the solute, as it is the proportionality constant in the law itself ($P = K_H \chi$). (Correct). - **Statement II:** The value of \(K_H\) depends strongly on the nature of the gas, the nature of the solvent, and the temperature. Changing the solvent changes intermolecular interactions, thus changing \(K_H\). (Incorrect). Conclusion: Option (2).
