Question 1

The activation energy for the following first-order reaction is 102 kJ/mol.
         N2O5(g) → 2NO2(g) + 1/2O2(g)
The value of the rate constant (k) is 1.35 × 10–4 s–1 at 35°C.  What is the value of k at 0°C?
◦ 8.2 × 10–7 s–1

◦ 1.9 × 10–5 s–1

◦ 4.2 × 10–5 s–1

◦ 2.2 × 10–2 s–1

◦ none of these

Question 2

The activation energy for the following reaction is 60. kJ/mol.
         Sn2+ + 2Co3+→ Sn4+ + 2Co2+
By what factor (how many times) will the rate constant increase when the temperature is raised from 10°C to 28°C?
◦ 1.002
◦ 4.6
◦ 5.6
◦ 2.8
◦ 696
