The popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. The apparent activation energy was determined to be about 34.2 kcalmol-1 with pre-exponential factor about 108 sec-1 for extent of reaction less than 0.5. %U https://ijcce.ac.ir/article_7660_b7cb5ec058d0ff703b2ebcca1f5cb84c.pdf
