NEETChemistryChemical Kinetics
Consider the following statements: I. Increase in concentration of reactant 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 = . IV. In k vs T is a straight line. V . In k vs 1 / T is a straight line. Correct statements are
Options
- AI and IV
- BII and V
- CIII and IV
- DII and III
Correct answer
B. II and V
Step-by-step solution
According to Arrhenius equation, k = Ae ^ - E _ a / RT when E _ a =0, k = A Also k vs 1 / T is a straight line with slope =- E ₂ / R . Statements (ii) and (v) are correct.
