WitrynaNote: If any of the reactants or products are gases, we can also write the equilibrium constant in terms of the partial pressure of the gases. We typically refer to that value as K p K_\text p K p K, start subscript, start text, p, end text, end subscript to tell it apart from the equilibrium constant using concentrations in molarity, K c K ... Witrynab) there will be less PbO2 remaining in vessel B. c) the amount of PbO2 remaining in each vessel will be the same. there will be less PbO2 remaining in vessel B. suppose that the gas-phase reactions A--> B and B-->A are both elementary processes with rate constants of 4.7 10^-3 and 5.8 10^-1 respectively.
