Chemistry unit 4

A starting compound A converts to intermediate B, which converts irreversibly to C. Each step is first order and no other reactions occur. A chromatographic detector gives equal signal per mole for all three. An experiment starting with 100 molar units of A yields these compositions (A, B, C): time 0: (100,0,0); time 1: (64,32,4); time 2: (41,46,13); time 3: (26,50,24); time 4: (17,48,35). Values are rounded. For this dataset, k1 = 2k2 and exp(-k2 × one time unit) = 0.8. The instantaneous rate of B production is k1[A], and its removal rate is k2[B].
