Assertion: In gaseous reaction, when the concentration of gases is expressed in terms of their partial pressures, then unit of rate will be atm s-1.
Reason: Units of rate are concentration time-1.
Answer & explanation
Correct answer: option 1
Units of rate are concentration time-1.
If concentration is in mole L-1 and time is in second, then the unit of rate will be mole L-1 s-1.
In gaseous reaction, when the concentration of gases is expressed in terms of their partial pressures, then unit of rate will be atm s-1.
