In the following reaction; x A → y B log 10 ⁡ - d A d t = log 10 ⁡ - d B d t + 0.3010…

In the following reaction; xAyB

log10-dAdt=log10-dBdt+0.3010

‘A’ and ‘B’ respectively can be:

  1. C2H4 and C4H8
  2. C2H2 and C6H6
  3. n-Butane and Iso-butane
  4. N2O4 and NO2

Solution

From the rate law:

log-dAdt=logdBdt+0.3010=log-dAdt=logdBdt+log2

-dAdt=2×dBdt

2AB and we know 2C2H4C4H8
