For low partial pressure of ozone (O₃), the adsorption of ozone on graphite surface is fully dissociative in nature, and follows Langmuir isotherm. Under these conditions, the dependence of the surface coverage of graphite (θ) on partial pressure of ozone (P₍O₃₎) is given by θ ∝ (P₍O₃₎)ˣ, the value of x is____________. (Up to two decimal places)
