5.
The fractional volume change between no conversion and complete conversion, for the isothermal gas phase reaction, 2A R , is
Answer: Option B
Explanation:
B doubles as the concentration of A i.e.., CA is doubled. If rate of reaction is proportional to CAn, then what is the value of n for this reaction ?
