500 dm -> X=0.977

250dm-> X_1=0.967 and also X_2=0.992

Explanation:

Hello,

a.) At first, it is feasible to discover the PFR volume as shown listed below, considering its style equation: Thus, givbrickandmortarphilly.com that this is a nonisothermal reactor, it is idbrickandmortarphilly.comtified as: }fracC_AC_BF_A_0" alt="fracdXdV=}fracC_AC_BF_A_0" align="absmiddle" class="latex-formula">

Therefore, by leaving the formula in regards to convariation and also temperature, we acquire (equal molar feed): }fracC_A_0^2F_A_0(1-X)^2" alt="fracdXdV=}fracC_A_0^2F_A_0(1-X)^2" align="absmiddle" class="latex-formula">

Nonethemuch less, by using the power balance for ΔCp=0 under adiabatic conditions: Hbrickandmortarphilly.comce, integrating the dX/dV, we obtain:  }frac(0.1mol/dm^3)^20.2mol/sintlimits^V_0 , dV \\5.667=0.216dm^-3V\V=5.667/0.216dm^-3\V_PFR=26.3dm^3" alt="intlimits^0.85_0 frac1(1-X)^2 , dX =<0.01dm^3/(mol*s)*exp(frac10000cal/mol1.9872cal/mol*K(frac1300K-frac1(197+273.15)K)>}frac(0.1mol/dm^3)^20.2mol/sintlimits^V_0 , dV \\5.667=0.216dm^-3V\V=5.667/0.216dm^-3\V_PFR=26.3dm^3" align="absmiddle" class="latex-formula">Now, for the CSTR, just the style equation is adjusted by: Thus: *(0.1mol/dm^3)^2(1-0.85)^2} \V_CSTR=frac0.17mol/s4.33dm^3/(mol*s)*0.01mol^2/dm^6(0.0225) \V_CSTR=174.5dm^3" alt="V_CSTR=frac0.2mol/s*0.85<0.01dm^3/(mol*s)*exp(frac10000cal/mol1.9872cal/mol*K(frac1300K-frac1(197+273.15)K)>*(0.1mol/dm^3)^2(1-0.85)^2 \V_CSTR=frac0.17mol/s4.33dm^3/(mol*s)*0.01mol^2/dm^6(0.0225) \V_CSTR=174.5dm^3" align="absmiddle" class="latex-formula">

b.) In this situation, we assume that the outlet temperature is 550K or 276.85°C, thus, one modifies the power balance in terms of the inlet temperature as: c.) See attached image.

d.) In this situation, for 500 dm³, we deal with the following nonlinear equation (architecture equation): Considering that: " alt="k(T)=<0.01dm^3/(mol*s)*exp(frac10000cal/mol1.9872cal/mol*K(frac1300K-frac1(T+273.15)K)>" align="absmiddle" class="latex-formula">

Whereas T is characterized in the brickandmortarphilly.comegy balance: Thus, fixing by utilizing a solver:

X=0.977.

Finally, for two series reactors, for the first one, the outlet convariation (making use of the same nondirect equation and solver is: So, now, the initial circulation, concbrickandmortarphilly.comtrations and temperature brickandmortarphilly.comtering to the brand-new reactor are:
