- Consider the following reaction at 25°C with the ΔG°’ = +1800 J/mol for the forward reaction.The molar concentrations at the beginning of the reaction were [A] = 19 mM and [B] = 10 mM.After 1 hour, the concentrations were [A] = 16 mM and [B] = 13 mM. Calculate the ΔG of the reaction at the 1 hour timepoint. Please round to 1 decimal point.Gas constant = 8.315 J/mol Karrow_forward(I) Why the physicochemical changes in liquid water caused by radiation is the key to understanding the biological effects of radiation? Please give a short, one-sentence explanation. (II) Name the three key stages of the physicochemical changes produced in liquid water due to radiation. (III) Briefly describe the three key stages. A one- or two-sentence explanation for each of the three key stages would be sufficient.arrow_forwardIn 2011, researchers showed that hypochlorous acid (HClO) generated by white blood cells kills bacteria.
