The value of Steric factor 'P' in the equation k = PZeE/RT usually ranges from ______________________?
Correct answer: A. 1.0 to 10-8
- A. 1.0 to 10-8
- B. 1.1 to 102
- C. 0.1 to 0.9
- D. None of these
Explanation
The steric factor accounts for the fraction of collisions having suitable molecular orientation and is usually much less than unity, with reported values extending roughly from 1 down to 10^-8. Hence option A gives the conventional range.
