Thermal decomposition of gaseous X2 to gaseous X at 298 K

Last updated: 6/30/2023

Thermal decomposition of gaseous X2 to gaseous X at 298 K takes place according to the following equation X 2 g 2X g The standard reaction Gibbs energy A G of this reaction is positive At the start of the reaction there is one mole of X2 and no X As the reaction proceeds the number of moles of X formed is given by B Thus Bequilibrium 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 mol The equilibrium constant Kp for this reaction at 298 K in terms of Bequilibrium is A 8p equilibrium 2 Bequilibrium B 88 quilibrium 4 equilibrium C equilibrium 48 2 Bequilibrium JEE Advanced 2016 3 124 40 D equilibrium 4 Bequilibrium JEE Advanced 2016 3 124 The INCORRECT statement among the following for this reaction is A Decrease in the total pressure will result in formation of more moles of gaseous X B At the start of the reaction dissociation of gaseous X2 takes place spontaneously C Bequilibrium 0 7
