What would the units of the rate constant k be in a second order equation if rate was measured in mol/(L x s)and all concentrations in mol/L a)L/(mol x s) b)L2/(mol2 x s) c)L3/(mol3 x s) d)mol2/(L2 x s) I think it's b) or a)

A solution prepared by mixing 16.7 mL of 0.760 M NaCl and 16.7 mL of 0.760 M KI was titrated with 0.380 M AgNO3 in a cell containing a silver indicator electrode and a saturated calomel reference electrode. (a) What is [Ag+] when 16.2 mL of 0.380 M AgNO3...

Given these standard reduction potentials at 25oC: Cr3+ + e- -> Cr2+ (E1^o = -0.407V) Cr2+ + 2e- -> Cr(s) (E2^o = -0.913V) Determine the standard reduction potential at 25oC for the half-reaction equation: Cr3+ + 3e- -> Cr(s) This seems like a really simp...

Look this is what i did You multiply the first reaction by -1 so you have -x for the reactant (since its what you started with) and you have y for the product (since it makes a gas) So enthalpy change is Delta H=>H(products)- H(reactants) which means its...

So it's C

Thanks for the help! But I'm curious - why multiply E2 by 2, and then divide the answer by 3?
