The fractional volume change between no conversion and complete conversion, for the isothermal gas phase reaction, 2A → R, is___________________?
Correct answer: B. -0.5
- A. 0.5
- B. -0.5
- C. 1
- D. 1.5
Explanation
For 2A → R, the change in total gas moles is 1 − 2 = −1 for every 2 moles of A consumed. Therefore the fractional volume-change coefficient is −1/2 = −0.5.
