Consider the reaction.I2(s) + 5F2(g) ⇋ 2IF5(g)What is the correct expression for Kc?

@X@user.full_name@X@ @GMU: A mixture containing an initial concentration of 0.1908 M for H2 and 0.1417 M for I2 is allowed to come to equilibrium (see reaction below). What must be the equilibrium concentration of HI?H2(g) + I2(g) → 2HI(g) Kc = 48.7000

Methyl acetate, CH3COOCH3 hydrolyzes in the water according to first order kinetics. Determine half-life and the rate constant.CH3COOCH3(aq) + H2O(l) → CH3OH + CH3COOH(aq)

What would be the expected rate law for the mechanism described below?1 NO(g) + 1/2O2(g) → NO2(g) fast 2 NO2(g) → NO(g) + O(g) fast 3 O2(g) + O(g) → O3((g) slow

@X@user.full_name@X@ @GMU: Determine the mole fraction of benzene if 5.2414 g of benzene, C6H6, was mixed with 7.33 g of cyclopentene, C5H8. MW(C6H6) = 78.114 g/mol; MW(C5H8) = 68.119 g/mol.

Determine if the reverse reaction for the energy level diagram is endothermic or exothermic and what the ΔH for the reverse reaction is.

@X@user.full_name@X@ @GMU: What is the mole fraction of magnesium nitrate, Mg(NO3)2, in an aqueous solution that contains 1.8905 g of magnesium nitrate dissolved in 22.6778 grams of water? MW(Mg(NO3)2) = 148.315 g/mol.
