NEET Chemistry Chemical Kinetics Questions Solved


The following data are obtained from the decomposition of a gaseous compound

Initial pressure, atm               1.6       0.8       0.4

Time for 50% reaction, min     80       113      160

The order of the reaction is

(A) 1.0                                       

(B) 1.5

(C) 2.0                                       

(D) 0.5

(B) t1/21t1/2=80113=p2p1n-1

where p2, p1are the initial pressures

80113=0.81.6n-1

Taking logarithms.

 log 0.7=(n-1) log 0.5

solving, n=1.5
