Question

The recolli C,H,(g) 2C, , (g) s-. What is the value of the rate has an activation energy of 262 kJ/mol. At 600.0 K, the rate

Answer 1

Answer #1

K1= 6.1×10E-8

Ea= 262 KJ/ mol= 262000j/mol

R= 8.314J/k/mol

T1=600K

T2= 785K

As per Arrhenius eq.

log(K2/K1)= -Ea/2.303R (1/T2-1/T1)

logK2/K1= -262000/2.303×8.314( 1/785-1/600)

logK2/K1=- 262000×-0.00039278/2.303/8.314

log K2/K1= 5.3746

K2/K1= antilog (5.3746)= 236919.06

K2= 6.1×10E-8×236919.0= 0.01445 s-1
