Rate of chemical reaction 2A (g) ⎯→ B (g) is defined as r B = 
where n B = no. of moles of B formed & C B = conc. of B, which of the following relation is correct -
A
r B = 
(v is not const.)
(v is not const.)
B
r B = 
(v is const.)
(v is const.)
C
r B = 
(v is not const.)
(v is not const.)
D
r B = 
(v is not const.)
(v is not const.)
