Without using numerical data, briefly describe how you could use pressure data to determine the rate for the reaction your group will be studying. Include an algebraic manipulation of the ideal gas law that fulfills your needs. HINT: it’s difficult to determine the volume of the gas in the apparatus. Is it necessary?
