Explanation / Answer

We wil use arrhenius equation to solve this problem.

The solution is given below

We will use the equation,

ln(k1/k2) = Ea/R(1/T2-1/T1)

where,

k1/k2 = 1/7

T2 = unknown

T1 = 345 K

Feed the values,

ln(1/7) = 54.69 x 1000 / 8.314 (1/T2-1/345)

solving for T2 = 384.24 K

Thus, the answer is 384.24 K
