Question 1

If Ea for a certain biological reaction is 50. kJ/mol, by what factor (how many times) will the rate of this reaction increase when body temperature increases from 37°C (normal) to 40°C (fever)?
◦ 1.15
◦ 1.20
◦ 2.0 × 105

◦ 1.0002
◦ 2.0

Question 2

In general, to calculate the activation energy for an elementary step given the rate constants at two different temperatures, which equation should be used?
◦ ln([A]t/[A]o) = – kt
◦ t1/2 = ln2/k
◦ ln(k1/k2) = Ea/R( (T1– T2)/T1T2)
◦ 1/[A]t = kt + 1/[A]o

◦ Rate = k[A]
