The Total solution for NCERT class 6-12
The decomposition of A intoproduct has value of k as 4.5 × 103 s−1 at10°C and energy of activation 60 kJ mol−1. At what temperaturewould k be 1.5 × 104 s−1?
From Arrhenius equation, weobtain
Also, k1 =4.5 × 103 s−1
T1 =273 + 10 = 283 K
k2 =1.5 × 104 s−1
Ea =60 kJ mol−1 = 6.0 × 104 J mol−1
Then,
= 297 K
= 24°C
Hence, k wouldbe 1.5 × 104 s−1 at 24°C.
