Biết hằng số tốc độ phân hủy H2O2: k= 7,3.10^-4 s^-1. Mất bao lâu để lượng mẫu [H2O2] bị phân hủy 2/3 so với thời điểm bắt đầu phản ứng. Biết phản ứng phân hủy H2O2 tuân theo động học bậc 1. H2O2 → H2O+ 1/2 O2

Ithink the answer is d.

Atp, shorthand for adenosine triphosphate, is the standard molecule for cellular enger in the human body. all motion and metabolic  processes  within the body begins with energy that is released from  atp, as its phosphate bonds are broken in cells through a  process  called hydrolysis.
