Polarization and nucleophile strength

I know that the more polarizable species are, the stronger the nucleophile is, but I'm not too sure about the general trend of polarizability across the periodic table. Can someone please help me out?

Catalysts and equilibrium constant

Would the equilibrium become greater in the presence of a catalyst?

relationship between Temperature and rate constants

based on the information in the course reader, the higher the temperature gets, the greater the rate constant is for the reaction, but then how come the answer to question 15.79 on page 661 says that at lower temperatures, the rate constant is larger?

Collision Theory and Transition State Theory

Should we be very familiar with Collision Theory and the Transition State Theory for the quiz next week?

units for heat capacity

are the units for heat capacity just kJ/C or can they also be kJ/K ?

Re: Negative change in entropy

yes because it is not a spontaneous reaction since delta S is negative so work has to be done on the system

Re: Problem 8.49

I believe you use 298.15 K because in these specific cases you have to use the SATP (standard ambient temperature and pressure) standard which is a temperature of 298.15 K and a pressure of 1 atm.
