Show that the Elovich equation for the rate of chemisorption can be integrated with respect to surface coverage (at constant pressure of the adsorbing gas to give: θ=α ln⁡〖(1+t)〗 Where t is the time from the start of the adsorption process and a and b are constants. If the activation energy for chemisorption is a linear function of surfce coverage, according to ????=????_0+????θ, derive the integrated form of the Elovich equation
