In a closed system : `A(s)hArr 2B(g)+3C`, if the partial pressure of C is doubled, then partial pressure of B will be

Temperature pressure and molar concentration are the three factors which can disturb the equilibrium in a reversible reaction. Their effect is governed by Le Chatelier's principle . Whereas high concentration of the reactants always favours the formation of the products irrespective of its nature the effect of temperature and pressure depends upon the nature of the reaction . pressure does not disturb the equilibrium point in a reaction in which the reactants and products have same number of moles in the gaseous state. In a closed system A (s) hArr 2B(g) +3C(g) if partical pressure of C is doubled then partial pressure of B will be :

For a reaction A(g) hArr B(g) at equilibrium . The partial pressure of B is found to be one fourth of the partial pressure of A . The value of DeltaG^(@) of the reaction A rarrB is
