Chemical Engineering Thermodynamics The reaction A (l) R(g) is allowed to reach equilibrium conditions in an autoclave. At equilibrium, there are two phases, one a pure liquid phase of A and the other a vapor phase of A, R and S. Initially A alone is present. The number of degrees of freedom are 1 2 3 1 2 3 ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics The root mean square speed of molecules of a gas is equal to (where, m = mass of the molecule K = Boltzman's constant, T = absolute temperature) √(2KT/m) √(3KT/m) 3KT/m √(6KT/m) √(2KT/m) √(3KT/m) 3KT/m √(6KT/m) 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
