The mechanism of the reaction, 2 N O ( g ) + 2 H 2 ( g ) → N 2 ( g ) + 2 H 2 O ( g ) , is 2 N O g + H 2 g → s l o w N 2 + H 2 O 2 H 2 O 2 + H 2 → f a s t 2 H 2 O Select the correct statement
Options
- Arate = k [ N O ] 2 [ H 2 ] 2
- Brate = k [ H 2 O 2 ] [ H 2 ]
- Con doubling the concentration of H 2 , keeping the concentration of NO constant, the rate will become double
- Dif the initial concentration of H 2 and NO is C 0 and after time 't' the concentration of N 2 is x, then rate
Correct answer
C. on doubling the concentration of H 2 , keeping the concentration of NO constant, the rate will become double
Step-by-step solution
As slowest step is the rate determining. Rate = k [ N O ] 2 [ H 2 ] So on doubling the concentration of H 2 without changing the concentration of NO, the rate will become double.
