NEET Chemistry Chemical Kinetics Questions Solved


Decomposition on NH3on heated tungsten yields the following data :

Initial pressure (mm)      65    105     y    185

Half-life (s)                   290     x     670   820

What are the values of x and y in that order ?

(A) 420 s, 110 mm                                                  

(B) 500 s, 160 mm

(C) 520 s, 170 mm                                                  

(D) 460 s, 150 mm

(D) Half lifeInitial pressure=29065=4.46

820185=4.43 The values nearly agree.

the reaction is of zero order.
