I think the answers is d, but not sure is it right or not. please correct me if i,m wrong.
1.)The rate constant for a reaction at 40.0 Celsius is exactly three times the rate constant at 20.0 Celsius. Calculate the activation energy for this reaction.
The Arrhenius equation is:
k = Ae-Ea/RT
which can be re-written as:
ln(k2/k1) = (Ea/R) ((1/T1) - (1/T2))
or
ln(k) = -(Ea/R)(1/T) + ln A
The activation energy, Ea =
a.)3.00 kJ/mol
b.)0.366 kJ/mol
c.)3.20 kJ/mol
d.)41.9 kJ/mol
e.)366 kJ/mol
