Chemical Engineering Thermodynamics In a reversible chemical reaction (where, Δx = number of moles of products-number of moles of reactants ) Addition of inert gas favours the forward reaction, when Δx is positive Addition of inert gas has no effect on the equilibrium constant at constant volume for any value of Δx (+ ve, - ve) or zero) All of these Pressure has no effect on equilibrium, when Δn = 0 Addition of inert gas favours the forward reaction, when Δx is positive Addition of inert gas has no effect on the equilibrium constant at constant volume for any value of Δx (+ ve, - ve) or zero) All of these Pressure has no effect on equilibrium, when Δn = 0 ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics High pressure steam is expanded adiabati-cally and reversibly through a well insulated turbine, which produces some shaft work. If the enthalpy change and entropy change across the turbine are represented by ΔH and ΔS respectively for this process: Δ H = 0 and ΔS = 0 Δ H ≠ 0 and ΔS = 0 Δ H ≠ 0 and ΔS ≠ 0 Δ H = 0 and ΔS ≠ 0 Δ H = 0 and ΔS = 0 Δ H ≠ 0 and ΔS = 0 Δ H ≠ 0 and ΔS ≠ 0 Δ H = 0 and ΔS ≠ 0 ANSWER DOWNLOAD EXAMIANS APP
