    A compound X undergoes two simultaneous first-order reactions as follows: X Y with rate constant k1 and X Z with rate constant k2. The ratio of k1/k2 at 40°C is 9.9. What is the ratio at 280°C? Assume that the frequency factors of the two reactions are the same.

    I used the equation ln k1/k2=(Ea/R)(T1-T2/T1*T2)

    my answer was 69.3 but this is wrong. can you assist me please?
