SOLVED: The reaction between fluorine and chlorine dioxide,F2(g) ClO2(g) → 2FClO2(g)Proceeds according to the following rate Law: r=k⋅PF2⋅PClO2where k= 0.0489 bar-1 s-1. In an isolation experiment, theinitial partial pressures are:PF2(t=0) = 0.04687 bar and PClO2(t=0) = 3.606 bar. Note: Ukeff means units of keff . You need to use a stringwith no spaces. For example enter gm3 as g*m^-3 or g/m^3.(a) Calculate the effective rate constant keff= Ukeff= (b) Compute the pressure of fluorine in
