A batch reactor is suitable for
A. Achieving cent percent conversion of reactants into products
B. Large scale gaseous phase reactions
C. Liquid phase reactions
D. Obtaining uniform polymerisation products in highly exothermic reactions
Answer: Option C
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. $$\frac{1}{{{{\text{k}}_{\text{e}}}{\text{ff}}}} = \frac{1}{{\text{k}}} + \frac{1}{{{{\text{k}}_{\text{g}}}}}$$

C. $$\frac{{0.693}}{{\text{K}}}$$
D. 6.93 K
