The reaction of `A_(2)` and `B_(2)` follows the equation
`A_(2)(g)+B_(2)(g)to2AB(g)`
The following data were observed
`{:(,[A_(2)]_(0),[B_(2)]_(0),"Initial rate of appearance of AB(g)(in" Ms^(-1)),(,0.10,0.10,2.5xx10^(-4)),(,0.20,0.10,5xx10^(-4)),(,0.20,0.20,10xx10^(-4)):}`
The value of rate constatnt for the above reaction is :
a) `2.5xx10^(-4)`
b) `2.5xx10^(-2)`
c) `1.25xx10^(-2)`
d) None of these
