Consider the following statements and arrange in order of true/false as given in the codes.
`S_1`:The rate of the reaction `AtoB` having the rate law-`(d[A])/(dt)=k[A][B]` when plotted against time will exhibit a maximum at some time.
`S_2`:A catalyst in a chemical reaction increases the forward `E_a` and decreases the backward `E_a`
`S_3`: A catalyst in a chemical reaction decreases both forward and backward `E_a`
`S_4`:For a first-order reaction, the time required to reduce successively the concentration of reactant by a constant fraction is always same.
A. TTTT
B. FFFF
C. FTFT
D. TFTT

Correct Answer - D
`S_1`:Because rate =0 at t=0 and `t=oo`
`S_2`:It decreases both by equal amount
`S_3`:It decreases both by equal amount
`S_4`:As `t_(1//2)` is constant for `1^(st)` order reaction
