Question

A) The activation energy of a certain reaction is 50.0 kJ/mol . At 23 ∘C , the rate constant is 0.0150s−1. At what temperature in degrees Celsius would this reaction go twice as fast?

Express your answer with the appropriate units

B) Given that the initial rate constant is 0.0150s−1 at an initial temperature of 23 ∘C , what would the rate constant be at a temperature of 110. ∘C for the same reaction described in Part A?

Express your answer with the appropriate units.

The Arrhenius equation shows the relationship
between the rate constant k and the temperature T in
kelvins and is typically written as
k= Ae-E/RT
where R is the gas constant (8.314 J/mol · K), A is
a constant called the frequency factor, and Ea is the
activation energy for the reaction.
However, a more practical form of this equation is
In - (A )
E
R
T,
which is mathmatically equivalent to
In =
k
ka
E,
T
where ki and k2 are the rate constants for a single
reaction at two different absolute temperatures (T1
and T2).
