Consider the following reaction:2Hbr (g)--> H2 (g) + Br2 (g)In the first 13.0 of this reaction, the concentration of dropped from 0.500 to 0.460 . Calculate the average rate of the reaction in this time interval.If the volume of the reaction vessel in part (b) was 0.500 , what amount of (in moles) was formed during the first 13.0 of the reaction?
Calculate the amount of heat required to completely sublime (turn from solid to gas) 25.0 g of solid dry ice (CO2) at its sublimation temperature. (the heat of sublimation is 32.3 kJ/mol)
What is the limiting reactant. How much of the nonlimiting reactant remains after the reaction is completed. Assume that all of the limiting reactant is consumed.
The first step in industrial nitric acid production is the catalyzed oxidation of ammonia. Without a catalyst, a different reaction predominates: 4NH3(g) + 3O2(g) ? 2N2(g) + 6H2O(g) When 0.0230 mol gaseous NH3 and 0.0250 mol gaseous O2 are placed ..
What is the total vapor pressure 4 at 20° C of a liquid solution containing 0.30 mole fraction benzene, C6H6, and 0.70 mole fraction toluene, C6H5CH3? Assume that Raoult's law holds for each component of the solution.
