Consider the given plots for a reaction ...

Consider the given plots for a reaction obeying Arrhenius equation (k and `E_a` are rate constant and activation energy, respectively)

Choose the correct option:

A

Both I and II are correct

B

I is wrong but II is right

C

I is right but II is wrong

D

Both I and II are wrong

Text Solution

Verified by Experts

The correct Answer is:
D
`k = Ae^(- (Ea)/(RT) )`
With increase of Ea, k decreases
With increase of temperature, k increases exponentially but the graph must have y – intercept
` therefore` Both I and II are wrong
