Suppose that the initial concentration of S232-O is 0.00300 M and the reaction time is 101 seconds in the iodine Clock reaction. What is the reaction rate?
Ever since volume is proportional to the number of moles present mole fractions of gases can be expressed as ratios of volumes at the same temperature and pressure. Compute the concentration of each gas in moles per liter at 0°C.
