3) 2A(g)+B(g)⇄2C(g)
Each with a concentration of 0.0100M . The following table shows the concentrations of the gases at equilibrium at a particular temperature.
[A]eq --> 0.01800
[B]eq-> 01400
[C]eq--> .0020
If the experiment is repeated at a higher temperature at which Kc is smaller, which of the following best describes the effect of the temperature change on the concentrations of the gases at equilibrium?
A)There will be a decrease in [A]eq that will be two times the decrease in [B]eq because A and B react in a 2-to-1 ratio.
B) [A]eq and [B]eq will remain constant, but [C]eq will increase because Kc decreased.
C) [A]eq , [B]eq , and [C]eq will all increase because Kc decreased.
D)There will be a increase in [A]eq that will be two times the decrease in [B]eq because A and B react in a 2-to-1 ratio.
What is the structure of butanoic propanoic anhydride
why the complex [Cr(NH3)6]3+ can also be considered high spin?
can you tell me what is the oxidation number of V in the complex [VCl4 (N (CH3) 3) 2)]Clwhich is the oxidation number of vanadium in the complex [VCl4(N(CH3)3)2]Cl ; does it have electrons in the d orbital;
6. A standard CaCO3 solution is prepared by dissolving 0.4193g in enough dilute HCl to effect solution and then diluted to 500ml solution. A 25.00ml aliquot requires 23.62ml EDTA solution for titration. A 25.00ml water sample determined for total hardness, requires 8.45ml of the EDTA solution using Eirochrome Black T indicator. Calculate the total hardness in the water sample expressed in ppm CaCO3. * *
) A buffer was prepared by mixing 1.00 mole of ammonia and 1.00 mole of ammonium chloride to form an aqueous solution with a total volume of 1.00 litre. To 500 mL of this solution was added 30.0 mL of 1.00 M NaOH. What will be the change in pH of this solution?
The isoelectronic [Pd(CO)4] 2+ complex mentioned in the last column of the paper has a significantly
higher CO IR stretching frequency (2248 cm−1 ) compared to [Rh(CO)4]+(2138 cm−1). Is this expected or not? Discuss and compare the two complexes.
The average Rh-CO bond distance in [(n6 C6H6)Rh(CO)2]+
is 1.88 Å, while [Rh(CO)4]+ has an average
Rh-CO bond distance of 1.95 Å. Is the longer Rh-CO distance in [Rh(CO)4]+ consistent with what the IR
stretching frequencies are telling you? Discuss.
Sketch out and electron count the following complexes: [(n6-C6H6)Rh(CO)2]+ and [Rh(CO)4]+
