![Biomolecular Signaling Hydrogen sulfide and nitrogen
monoxide can act as signaling agents in living cells. NO is
often bound in a molecule named 5-nitrosoglutathione
(GSNO) and is released in a reaction with H2S, producing
glutathione (GSH) and thionitrous acid (HSNO):
GSNO(aq) + H2S(aq) → GSH(aq) + HSNO(aq)
The rate of the reaction at 25°C was determined by
following the rate of consumption of H2S:
a. Calculate the average rate of the reaction between t = 0.0
