say we have a reaction N2O4 reversible 2NO2
for this reaction,if initial number of moles of N2O4 is 'a' can we write
t = 0 a -
at equilbrium a-x 2x
similarly can we do the same for pressure? i.e. if initial pressure is p,then can we say?
t=0 p -
at equilbrium p-y 2y
if yes why? and is x=y,i.e is the number of moles of x dissociated equal to decrease in pressure of reactant? and is this method valid for all reversible reaction irrespective of the stoichiometric coefficient of reactants and products
