For a mixed flow reactor operating at steady state, the rate of reaction is given by
A. $$\frac{{{{\text{F}}_{{{\text{A}}_{\text{0}}}}}}}{{\text{V}}} - \frac{{{\text{d}}{{\text{C}}_{\text{A}}}}}{{{\text{dt}}}}$$
B. $$\frac{{{{\text{F}}_{{{\text{A}}_{\text{0}}}}}}}{{\text{V}}} + \frac{{{\text{d}}{{\text{C}}_{\text{A}}}}}{{{\text{dt}}}}$$
C. $$\frac{{{{\text{F}}_{{{\text{A}}_{\text{0}}}}}}}{{\text{V}}} \cdot {{\text{X}}_{\text{A}}}$$
D. $$ - \frac{{{\text{d}}{{\text{C}}_{\text{A}}}}}{{{\text{dt}}}}$$
Answer: Option C
This Question Belongs to Chemical Engineering >> Chemical Reaction Engineering
A. $${{\text{k}}_{\text{e}}}{\text{ff}} = {\text{k}} + {{\text{k}}_{\text{g}}}$$
B. $${{\text{k}}_{\text{e}}}{\text{ff}} = \frac{{{\text{k}} + {{\text{k}}_{\text{g}}}}}{2}$$
C. $${{\text{k}}_{\text{e}}}{\text{ff}} = {\left( {{\text{k}}{{\text{k}}_{\text{g}}}} \right)^{\frac{1}{2}}}$$
D. $$\frac{1}{{{{\text{k}}_{\text{e}}}{\text{ff}}}} = \frac{1}{{\text{k}}} + \frac{1}{{{{\text{k}}_{\text{g}}}}}$$
