For the reaction NO+03-->NO2+O2, the reaction was found to be first order both with rspect to NO and O3 (expressing concentrations as molarity) What are the units of the rate constant K for this reaction?
A certain quantity of a gas occupies 61.3 mL at 68 ?C. If the pressure remains constant, what would be the volume of the gas at 128 ?C?
calculate the final molarity of the solution that results when 125 ml of .200 M HCL is diluted to 1.00L
A gas occupies a volume of 1.0 L at a temperature of 27°C and 500 torr pressure. calculate the volume of the gas if the temperature is changed to 60°C and the pressure to 700 torr
The rate constant of some reaction double with 10 degree rise in temperature. Assume that a reaction takes place at 295 K and 305 K. What must the activation energy be for the rate constant to double as described?
What is the half-life of a second-order reaction in which 45.0% of the original concentration of 1.00 M remains after 325 seconds?
Calculate the pressure when temperature is increased to 383 0C and volume of container keeps constant?
A pound of coffee beans yields 48 cups of coffee. How many milliliters of coffee can be obtained from 1 g of coffee beans?
The equilibrium constant Kc for the decomposition of phosgene, COCl2, is 4.63 10-3 at 527°C. COCl2(g) CO(g) + Cl2(g) Calculate the equilibrium partial pressure of all the components
Magnesium Hydroxide is a slightly soluble substance. If the pH of a saturated solution of Mg(OH)2 is 10.49 at 25 degrees celcius, calculate Ksp for Mg(OH)2.
What pH would you make the water layer in order to cause the acid to dissolve in the ether layer and the amine to dissolve in the water layer? d. How would you purify a mixture of benzoic acid, chlorobenzene, and cyclohexylamine?
An object has a mass of 5.95g. Assuming the density of water is 1 g/mL, what is the volume of the object including air?
Consider the following reactions and select the false statement below. CO2(g) + OH?(aq) ? HCO3?(aq) Cr3+(aq) + 6H2O(l) ? Cr(H2O)63+(aq) A. in Cr(H2O)63+ the Cr3+ is attracted to the H2O molecules via ion-dipole intermolecular forces
