Consider the following reaction, and its value of K : 2 HBr(g) + Cl2(g) ? 2 HCl(g) + Br2(g) K = 0.065 a. Sketch the reaction energy diagram for this reaction (reactants on the left, products on the right, and transition state in the middle). b. Compare the amounts of reactants and products that will be present when the system reaches equilibrium. c.What will happen to the amount of Cl2 in the system if HCl is removed from the mixture? d. For this reaction, will the value of DG be positive, negative, or zero?
Why would we obtain the same equation of state for linear molecules and non-linear molecules ( that is, taking rotations and vibrations into account?
In a particular sample, the C13 NMR spectrum showed a signal 25ppm and another signal at 72.3 ppm. if the reference frequency for C13 on the instrument were 25.1 MHz what is the difference between the frequency of each signal and the reference fre..
If what makes an acid strong is the extent of dissociation, at what sorts of concentrations (high or low) do weak acids behave more like strong acids
A voltaic cell SIMILAR to that shown in Figure 20.5 is constructed. One electrode compartment consists of a silver strip placed in a solution of AgNO3,
A strip of zinc metal having a mass of 2.00 g is placed in an aqueous solution containing 2.5 g of silver nitrate, causing the following reaction: Zn +2AgNO3-----2Ag +Zn(NO3)2
The lab was a "Two-Base Extraction" A mixture of benzoic acid, 2-naphthol, and naphthalene was extracted with sodium bicarbonate and followed by sodium hydroxide.
At a pressure of 1.00 atm and a temperature of 20 degree Celsius, 1.72 g CO2 will dissolve in 1 L of water. How much CO2 will dissolve if the pressure is raised to 1.35 atm and the temperature stays the same?
What is the mass of a magnesium block that measures 2.3 cm * 3.5 cm * 1.5 cm? The density of magnesium is 1.738 g/cm^3
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more com- plicated, but this is a reasonable ?rst ap proximation.)
In photosynthesis, plants from glucose (C6H12O6) and oxygen from carbon dioxide and water, Part B, Calculate delta H rxn at 15 degree C
?Hf0 for the formation of rust (Fe2O3) is -826 kJ/mol. How much energy is involved in the formation of 5 grams of rust.
