Peroxodisulfate S2O8 2- reacts with thiosulfate (S2O3 2-) according to the following reaction (S{2}O{8} {2-} + 2S{2}O{3} {2-} -->2SO{4} {2-} + S{4}O{6} {2-})
a) Illustrate how the change in peroxodisulfate with time is related to the change in concentration with time of the other three species.
b) Explain if the reaction is elementary and irreversible define what is the overall order of the reaction.
Clearly sketch both a Michaelis-Menten plot (initial velocity vs. substrate concentration) and a Lineweaver-Burke (double-reciprocal) plot showing the activity of an enzyme
A student measures the standard enthalpy change for reaction (C2H4(g) + H2O(g) CH3CH2OH(g)) to be -52.8 kJ :Calculate the standard enthalpy of formation.
If the following substance is dissolved in pure water, will the solution be acidic and Explain Ammonium sulfate-((NH4)2SO4)
An 80.0-gram sample of a gas was heated from 25 °C to 225 °C. During this process, 346 J of work was done by the system and its internal energy increased by 7805 J. What is the specific heat of the gas
Approximate the percent increase in waist size when a 155 lbs person gains 40 lbs of fat. Assume the volume of a person can be modeled by a cylinder that is 4 ft tall. The average denisty of a human is 1g/cm3 and the average density of fat is .918..
A sample of gas is collected over water at c and mm Hg. The collected gas occupies 130 mL. The vapor pressure of water at 23.5 c is 21.7 mm Hg. The approximate molecular weight of this gas
question the solubility of ammonium chloride at 30.0 c is 41.1 g per 100 g of water. what is the maximum amount in
what is the value of kf for acetic acid given that its freezing temperature is 16.6 c and its density is 1.049 gml?
Carbon-dating evaluates the ratio of radioactive carbon-14 to stable carbon-12. Given the amount of carbon-12 contained a measured sample cut from the document, there would have been about 1.3 × 10-12 grams of carbon-14 in the sample when the parc..
An additional atm pressure of HI is admitted to the con- tainer, and it is allowed to come to equilib- rium again. What is the new partial pressure of HI?
A titration was performed to standardize an EDTA solution. use the following data to calculate the molarity of the EDTA solution. A 50.00 mL aliquot of a standard solution containing 0.025000 M Ca^2+ required 39.92 mL of EDTA to reach a distinct b..
