Extra Credit for Jivhan question: If you could give Jivhan one piece of advice to prevent him from having another episode like this, what would it be and why are you suggesting this ?

A sealed, rigid, adiabatic vessel contains an ideal gas undergoing the exothermic first-order reaction A→B with ΔHr=−50,000 J/mol\Delta H_r = -50{,}000\ \text{J/mol}, initial concentration CA0=2.0 mol/LC_{A0} = 2.0\ \text{mol/L}, constant heat capacity Cv=25 J/(molK) and initial temperature T0=300 K. Assuming constant volume and that total moles remain unchanged, derive the differential equation relating temperature T to conversion XX and determine the final temperature when the reaction reaches 80% conversion.

A radio station operates with a radio frequency of 101.5 MHz.   What is the wavelength of this radiation in meters? (hint: 1MHz = 106 Hz) Use correct number of significant figures. [ans1]   What is the energy of the radio frequency in kJ in the problem above? Use scientific notation and the correct number of significant figures.
