Chemical Reaction Engineering During manufacture of H₂SO₄, the oxidation of SO₂ to SO₃ by oxygen is an en- dothermic reaction. The yield of SO₃ will be maximised, if the Temperature is increased and pressure is reduced Temperature is reduced and pressure is increased Temperature is increased Pressure is reduced Temperature is increased and pressure is reduced Temperature is reduced and pressure is increased Temperature is increased Pressure is reduced ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The response curve for a step input signal from a reactor is called C-curve. The variance of C-curve in a 'tanks in series model' comprising of 'm' tanks is equal to m² √m 1/m m m² √m 1/m m ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering If the catalyst pore size is small in comparison with the mean free path, collisions with the pore wall controls the process'. The diffusivity under this condition is called 'Knudsen diffusivity', which is affected by the Pressure Neither A nor B Both A & B Temperature Pressure Neither A nor B Both A & B Temperature ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering When the reaction is dominated by in-traparticle diffusion, the apparent order of reaction (nD) as measured is related to the true order (n) as ND = n/2 ND = (n + 1)/2 ND = n + 1 None of these ND = n/2 ND = (n + 1)/2 ND = n + 1 None of these ANSWER DOWNLOAD EXAMIANS APP
