Answer:
see attached
Explanation:
Two methods are shown in attached notes... Method I is based upon Experimental Rate Trends; Method II is the 'Ratio Method'.
Assuming ideal gas law applies to the problem, we find the pressure from the given volume, temperature and number of moles. The ideal gas equation is PV=nRT. R is 0.0821 L atm/ mol K. Substituting the data given, P= (2.50 moles)(0.0821 L atm/ mol K)(27+273 K)/(50 L)= 1.2315 atm. This is equivalent to 936 mm Hg.
