For the decomposition reaction: N(2)O(...

For the decomposition reaction:
`N_(2)O_(4(g))rarr 2NO_(2(g))`, the initial pressure of `N_(2)O_(4)` falls from `0.46` atm to `0.28` atm in `30` minute. What is the rate of appearance of `NO_(2)`?

A

`12 xx 10^(2)"atm"."min"^(-1)`

B

`1.2 xx 10^(2) "atm"."min"^(-1)`

C

`1.2 xx 10^(-2)"atm"."min"^(-1)`

D

`1.8 xx 10^(-1) "atm"."min"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`1/2 (d[NO_(2)])/(dt) = [0.28 - 0.46]/30`
`(1//2d[NO_(2)])/(dt) = 6 xx 10^(-3)`
`1.2 xx 10^(-2) atm. "Min"^(-1)`
