In order to experimentally determine order, initial rate method can be used Once order is determined integrated rate law can be obtained by using concentration of reactants Based on this information and data given below,
`{:(,"[A] Molarity",,"[B] Molarity",,Rate of Reaction[Msec^(-1)]),("1",10^(-2)M,,3xx10^(-3)M,,2xx10^(-2)),("2",2xx10^(-2)M,,3xx10^(-3)M,,4xx10^(-2)),("3",2xx10^(-2),,6xx10^(-3)M,,8xx10^(-2)):}`
Answer the question which follow
Reaction: `A(g)+B(g) rarr C(g)`
What will be the time taken for half of the 'A' initially taken to consume if at the same temperature reaction is started taking [A] and [B] to be at 2 M concentration?

Options

A. `4/3xx10^(-3)` sec
B. `3/4xx10^(-3)` sec
C. `1/8xx10^(-4) sec`
D. `8/3xx10^(-3) sec`

Answer

B
