a. Calculate the total pressure at equilibrium when 4.45 g of CO2 is introduced into a 10.0 L container and heated to 1200 K in the presence of 2.00 g of graphite.
b. Repeat the calculation of part a in the presence of 0.50 g of graphite.
Solution 75EStep 1Molarity is the number of moles of solute present in 1 Litre of solution.It can be calculated by the following formulae.In the above formulaeThe study of reactant and products in a chemical reaction is known as Stoichiometry. Moles areused to calculate the amount of product formed or amount of reactant required to form theproduct in the reaction, called mole method .The stoichiometric coefficients of a chemical equation are assumed as no. of moles of thesubstance as relative number of molecules are same as the relative number of moles.It is stated by Dalton's law of partial pressures that the total pressure exerted by a mixture ofgases is the sum of partial pressure of each individual gas. The gas behaves as ideal gas. It isrepresented as follows:\n
