Consider the following reaction: `2 NO _(2) (g) to 2 NO (g) + O _(2) (g)`
In the figure below, identify the curves X, Y, and Z associated with the three species in the reaction
: `X = NO , Y =O _(2) , Z = NO _(2)` , `X = O _(2) Y = NO , Z = NO _(2)` , `X = NO _(2), Y = NO, Z = O _(2)` , `X = O _(2), Y = NO _(2), Z = NO`

A

`X = NO , Y =O _(2) , Z = NO _(2)`

B

`X = O _(2) Y = NO , Z = NO _(2)`

C

`X = NO _(2), Y = NO, Z = O _(2)`

D

`X = O _(2), Y = NO _(2), Z = NO`

Text Solution

Verified by Experts

The correct Answer is:
A
The concentration of X is increasing hence it is product, while concentration of Z decreases therefore it is reactant. The concentration of Y is less than X, Hence , Y must be `O _(2)` and X must be NO because 2 mol of `NO_(2)` produces 2 mol of NO and 1 mol of `O _(2).` Therefore, `X = NO, Y = O _(2) and Z = NO _(2).`
