The rate constant of a reaction is 2.75*10^-5 L/mol*s at 195 c and 3.75*10^-3 L/mol*s at 258 c. What is the activation energy of the reaction?
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
Suppose that the solvent ethanol could serve to replace the methanol in this process, but at the expense of double the concentrations of the solvent in the atmosphere.
