Which two the following would be evidence that the mechanism shown below is occurring? When Zno encounters formic acid (HCOOH), the following decomposition reaction occurs. ZnO(aq) + HCООН(9) — Н(g) + CООН() slow step H(g) + COOH(g) CO2(g) + H2(g) + ZnO(aq) fast step HCOOH(g) CO2 + H2(g) overall reaction A The overall reaction is exothermic The addition of the two steps of the В mechanism lead to the overall reaction equation C The overall reaction is endothermic The presence of ZnO(s) increases the rate of the overall reaction E ZnO is an intermediate in the reaction
(d) On the other hand, in quantum physics/mechanics/chemistry, energy is assumed to be quantized and distributed. Therefore, virtually any reaction can take place in a cell even though some reactions remain exceedingly slow (or not possible on the time-scale of life processes) without enzyme catalysis. Explain why.

The acid-catalysed conversion of γ-hydroxybutyric acid (GHBA) into its lactone, γ-butyrolactone (GBL) is a reversible reaction. The GHBA to GBL forward reaction is first-order with respect to the GHBA concentration; the GBL to GHBA reverse reaction is first-order with respect to the GBL concentration. An experimental study of the kinetics of this reaction was undertaken in 0.2 mol L-1hydrochloric acid (HCl) at 298 K. The initial concentration of GHBA was 18.23 × 10-3mol L-1 . The concentration of GBL in solution was followed as a function of time (t), as indicated in Table B.3: Time/min 0 21 36 50 65 80 100 ∞ GBL Concentration / 10-3 L-1 0 2.41 3.73 4.96 6.10 7.08 8.11 13.28 Use the data in Table B.3 to determine the equilibrium constant and the first-order rate constants for both forward and reverse reactions.
