`2X(g) rarr 3Y(g)+2Z(g)`
`{:("Time (in min)",0,100,200,):}`
`|{:("Partial pressure of X (mm Hg)",800,400,200,),("Assuming ideal gas condition, calculate",,,,):}|`
(a) Order of reaction
(b) Rate constant
( c) Time taken for `75%` completion of reaction
(d) Total pressure when `p_(x) = 700 mm`

Text Solution

Verified by Experts

(i) Data shows that half of the reaction is contant, i.e. 100 min , hecne it is a first order reaction ,
(ii) `k=(0.693)/(t_(1//2))=(0.693)/(100)=693xx10^(-3)"min"^(-1)`
(iii) `t_(75%),i.e.,t_(3//4)=2xxt_(1//2)=2xx100=200min`
`2X(g)rarr3Y(g)+2Z(g)`
`{:(t=0,800,0,0),(dt,800-2X,3X,2X):}`
Total prssure =800-2X+3X+2X=800+3X....(i)
800-2X=700
X=50
`:.` Total pressure `=800+3xx50=950` mm Hg
