The dimensions of rate constant for reaction 3A → B are (l/gm mole)/min. Therefore the reaction order is______________________?
Correct answer: C. 2
- A. 0
- B. 1
- C. 2
- D. 3
Explanation
For an nth-order reaction, k has units of concentration^(1−n) per time. Since L mol⁻¹ min⁻¹ equals concentration⁻¹ time⁻¹, 1−n = −1 and n = 2.

In a semi-batch reactor __________________?
Pure ethanol vapor is fed to a reactor packed with alumina catalyst, at the rate of 100 kmole / hr. The reactor products comprise: ethylene: 95 kmole / hr, water vapour: 97.5 k mole / hr and diethyl ether: 2.5 kmole/hr. The reactions occuring can be represented by: C2H5OH → C2H4 + H2O 2C2H5OH → C2H5 - O - C2H5 + H2O The percent conversion of ethanol in the reactor is________________?
Second order consecutive irreversible reaction as shown in the bellow figure, were carried out in a constant volume isothermal batch reactor with different initial feed compositions. Reactor temperature was same in all the cases. In experiments where the ratio of concentration of B to that of A in the initial feed was less than 0.5, the concentration of B increased first, reached a maximum and then declined with time. However, for all experiments where this concentration ratio was 0.5 or above, concentration of B decreased monotonically with time right from the beginning. What is the ratio of the two rate constants (k1/k2) ?
