- The equation of the double reciprocal plot is y = 0.5294 x + 1.4960. What is the value of vmax (in M/s)? The substrate concentration is given in units of molarity (M) and reaction velocity has units of molarity per second (M/s). (Report to three significant figures)Calculate the Keq (report up to two decimal places and do not use scientific notation) for the net reaction at 298.15K. (see attached image) Note: R = 1.98 x 10 -3 kcal/mol-KThe formation constants at 25°C for Fe(CN)4-6 and Fe(EDTA)2– are 1.00 x 1037 and 2.10 x 1014, respectively. Answer the questions below. 1) Calculate K under standard conditions for the reaction Fe(EDTA)2−(aq) + 6CN−(aq) ----> Fe(CN)4−6(aq) + EDTA4−(aq) 2) Calculate ΔG° for the reaction. (kJ/mol)
