When Ethyl Chloride, CH₃CH₂Cl, Is Dissolved in 1 $\rightarrow$ CH₃CH₂OH + Cl^-
at 25°C the Reaction Is First Order

question 43

Multiple Choice

When ethyl chloride, CH₃CH₂Cl, is dissolved in 1.0 M NaOH, it is converted into ethanol, CH₃CH₂OH, by the reaction CH₃CH₂Cl + OH^- $\rightarrow$ CH₃CH₂OH + Cl^-
At 25°C the reaction is first order in CH₃CH₂Cl, and the rate constant is 1.0 * 10^-3 s^-1. If the activation parameters are A = 3.4 * 10¹⁴ s^-1 and E_a = 100.0 kJ/mol, what will the rate constant be at 28°C? (R = 8.314 J/mol • K)

• A) 3.8 * 10¹⁴ s^-1
• B) 1.1 *10^-3 s^-1
• C) 8.9 *10² s^-1
• D) 9.2*0 10^-3 s^-1
• E) 1.5 *10^-3 s^-1
