5.0 mL of reactant A (0.10 M) was added to 5.0 mL of reactant B (0.25 M). The reaction was monitored until all of A was consumed, according to the reaction A+2B — C. The measured reaction time was 51 seconds. What is the rate of this reaction? x 10 M/s
5.0 mL of reactant A (0.10 M) was added to 5.0 mL of reactant B (0.25 M). The reaction was monitored until all of A was consumed, according to the reaction A + 2BC. The measured reaction time was 39 seconds. What is the rate of this reaction? x 10 Ms
4. You added 0.05 mL of 0.10 M AgNO, to 4.0 mL of 2.0 M NaCl, and formed a saturated solution of AgCl (s): AgCl (s) 7 Ag+ (aq)+CF (aq) K=Ksp Using this saturated solution as the test solution you set up the following cell AgAg (test solution after reaction)||Ag (1.0M) Ag and measured Ecell = 0.61 V. (a) Using the measured value of Ecell and Eq (15), calculate the equilibrium (Ag l (i.e. of the test solution after reaction)....
