The reaction : 
is an elementary process. In an experiment, the
initial partial pressure of A and 
are 
and 
. When 
, the rate of reaction relative to the initial rate is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Initial pressure at 
0.60 0.80 0 0
Pressure at 
Final pressure 0.40 0.40 0.20 0.20
Since it is an elementary reaction. Therefore,
Rate of reaction 
Rate of reaction (initial) 
…… .(i)
Rate of reaction (final) 
…… .(ii)
