Tính thời gian (phút) để nồng độ metylamin giảm đi 3,9 lần
Bài 1: Ở 913K, hằng số tốc độ phản ứng đehiđro hoá metylamin :
H3CNH2 (k) => HCN(k) + 2H2(k)
bằng 0,0053 s-1 Tính thời gian (phút) để nồng độ metylamin giảm đi 3,9 lần
Bài 2: At 518°C, the half-life for the decomposition of a sample of gaseous acetaldehyde (ethanal) initially at 363 Torr was 410 s. When the pressure was 169 Torr, the half-life was 880 s. Determine the half-life (s) of acetaldehyde if its initial concentration was 0,032 mol/L.
