In the lab activity, the reaction rate was determined by the appearance of a product. However, the reaction rate can also be determined by the disappearance of a reactant. --aructi or Rate-a[Reactant] In each situation below, you are given a rate measured by the appearance of one component of the reaction and are asked to predict the rate of appearance or disappearance of another component, based on logic and stoichiometric relationships. For example, if the reaction is as follows: A +2B Products For every mole of A that is used, 2 moles of B are used so the rate of disappearance of B is twice the rate of the disappearance of A. This may be expressed as: Rate =-=-N2(g) + 3H2 (g) ? 2NH3(g) The reaction rate is measured as 0.032 M NHy/s. Determine the rate of disappearance of N2 and the rate of disappearance H2. Explain how you arrived at your answers. CH4(g)+202(g) -CO2(g)+2H,0(8) The reaction rate is measured as 2.6 M CH/s. Determine the rate of appearance of CO2 and the rate of appearance of H20. Explain how you arrived at your answers
