Give the structure that corresponds to the following molecular formula and 1H NMR spectrum: C7H12Cl2: ? 1.07 (integral = 6203, s); ? 2.28 (integral = 1402, d, J = 6 Hz); ? 5.77 (integral = 700, t, J = 6 Hz). Note: The integrals are given in arbitrary units.
Gas cylinder A has a volume of 48.2 L and contains N2(g) at 8.35 atm at 25 ºC. Gas cylinder B, of unknown volume, contains He(g) at 9.50 atm at 25 ºC
To find the value of the equilibrium constant at each temperature you must first find the value of G0 at each temperature by using the equation G0 = H0 - TS0 For this reaction the values are H0 = +88.3 kJ/mol and S0= 151.3 J/mol*K
