Consider the following statements. i) Increase in concentration of rectant increases the rate of a zero order reaction. ii) rate constant k is equal to collision frequency a if `E_(a)=0` iii) rate constant k is equal to collision frequency A if `E_(a) = infty`. iv) In k vs T is a straight line. v) In k vs `1//T` is a straight line. Correct statements are:A. i) and iv)B. ii) and v)C. iii) and iv)D. ii) and iii) |

Answer» Correct Answer - B i) For zero order reaction the increases in concentration of reactants does not affect reaction rate. ii) According to Arrhenius equation. `k=Ae^(-Ea//RT)` Where `E_(a) =0, k=A` iii) When `E_(a) = infty, klt A` iv) In k vs t is not a straight line v) In k vs `1//T` is a straight line with slope `=(-Ea//R)` Statements (ii) and (v) are `DeltaH` correct. |
