Thermal decomposition of gaseous X_(2) to gaseous X at 298 K takes place according to the following equation : X_(2)(g) 2X(g) The standard reaction Gibbs energy, Delta_(r)G°, of this reaction is positive. At the start of the reaction, there is one moe of X_(2) and no X. As the reaction proceeds, the number of moles of X formed is given by beta. Thus, beta_("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)) The Incorrect statement among the following, for this reaction is

Answer»

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
`beta_("equilibrium")=0.7`
`K_(C)lt1`

Answer :C
