Answer 1

_37._ Ž 2 HI(g) H₂ (9) + I go to= CHIJ by J123 On increasing temperature , ke decreases. So, the equilibrium shifts in such a way that, ke value semains unchanged 0 This ů a exotheomic Heaction A I I So, according to le chatelies's principle the equilibrium will more to left with increasin temperature. Less HI will be formed and equilibrium mixture will contain mose unreacted H₂ & 2 So, option 1 is connect
