, Decrease in the total pressure will result in formation of more moles of gaseous X

, At the start of the reaction, dissociation of gaseous X 2 takes place spontaneously

and equilibrium = 0.7

. ONLY ONE of these four options is correct • For each question, marks will be awarded in one of the following categories: Full Marks : +3 If only the bubble corresponding to all the correct option is darkened Zero Marks : 0 In all other cases. PARAGRAPH 1 Thermal decomposition of gaseous X 2 to gaseous X at 298 K takes place according to the following equation: The standard reaction Gibbs energy, r G°, of this reaction is positive. At the start of the reaction, there is one mole of X 2 and no X. As the reaction proceeds, the number of moles of X formed is given by . Thus, equilibrium is the number of moles of X formed at equilibrium. The reaction is carried out at a constant total pressure of 2 bar. Consider the gases to behave ideally. (Given: R = 0.083 L bar K -1 mol -1 ) (i) The equilibrium constant K p for this reaction at 298 K, in terms of P equilibrium , is (ii) The INCORRECT statement among the following, for this reaction is K c < 1
