Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which of the following correctly represent/s the units of rate of reaction? (1)\[mol\,{{L}^{-1}}{{s}^{-1}}\] (2) \[L\,mol\text{ }{{s}^{-1}}\] (3) \[atm\text{ }{{s}^{-1}}\] (4)\[atm\,\,mo{{l}^{-1}}\text{ }{{s}^{-1}}\]A) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: D
Solution :
\[Rate=\frac{change\,in\,concentration}{time}\] \[\therefore \]Units of rate\[=\frac{mol/L}{s}\] \[=mol\,{{L}^{-1}}{{s}^{-1}}\] or units of rate\[=\frac{atm}{s}=atm\,{{s}^{-1}}\]
