Consider the following reaction:
`2NO_(2)(g) rarr 2NO(g)+ O_(2)(g)`
In the figure below, identify the curves `X,Y,` and `Z` associated with the three species in the reaction

A

`X = NO, Y = O_(2), Z = NO_(2)`

B

`X = O_(2), Y = NO, Z = NO_(2)`

C

`X = NO_(3), Y = NO, Z = O_(2)`

D

`X = O_(2), Y = NO_(2), Z = NO`

Text Solution

Verified by Experts

The correct Answer is:
A
`r = - ( 1)/(2)(d[NO_(2)])/(dt) = + 1/2(d[NO])/(dt) = + (d[O_(2)])/(dt)`
`:. NO_(2)` is reactant so ` (Z)`
rate of dis appearance of ` NO_(2)` = rate of formation of `NO`
So NO is (X)
