A laser emits a line at 632.8 nm. If the cavity is 12 cm long, how many modes oscillate in the cavity? How long does it take for the radiation to travel the entire cavity? What is the frequency difference between 2 consecutive modes?(refractive index of the medium n = 1).

The number of microstates corresponding to each macrostate is given by N. The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?

For the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.
