320085 The rate constant is given by the equation $k = p z e^{- E_{a} / R T}$ . Which factor should register a decrease for the reaction to proceed more rapidly?

1

T

2

Z

3

E_{a}

4

P

Explanation:

Lower is the activation energy, $E_{a}$ faster is the reaction.

CHXII04:CHEMICAL KINETICS

320086 Assertion :
Arrhenius parameter $(A) = P$ (steric factor) $\times z$ (collision frequency)
Reason :
On increasing temperature, the value of A increases.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

3 Assertion is correct but Reason is incorrect.

4 Assertion is incorrect but reason is correct.

Explanation:

Collision theory is for bimolecular reactions.Zero order reaction, rate constant units are mol. lit $^{-}$ sec $^{-}$ photo chemical reaction is an example of zero order reaction. Intercept in Arrhenius plot is $\ln A$ .
Order of reaction can be $+ ve, - ve$ , zero or dfractional.
