In the following reaction represented by the net ionic equation, the rate of reaction of CN– is 0.451 mol/L·min. What is the rate of reaction of MnO4– (mol/L·min)? Report your answer to the thousandths place and do not include units.

( the reaction 2 HgO(s)--> 2 Hg(1) + O2(g) we measure the evolution of gas to determine the rate of reaction. At the beginning of the reaction (at 0 minutes), 0.020 L of O2 is present. After 15 minutes the volume of O2 is 0.35 L. What is the rate of reaction in L/min? For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

Consider the following general reaction for which gases A and B are mixed in a constant volume container: A(g) + B(g) -> C(g) + D(g) Match what happens to the rate of the reaction under the following changes: (consider each change separately) v all of gas B is removed from the container more gas A is added to the container the temperature of the container is increased there is no change to the reaction rate ya catalyst is added to the container I. the reaction proceeds at a faster rate v gas D is also added to the container the reaction proceeds at a slower rate II. some of gas B is removed from the container Iy the reaction does not proceed at all the volume of the container is increased

(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion.Reaction rates increase with increasing temperature.The slowest step in a reaction is called the rate-determining step.Catalysts increase reaction rates.The fastest step in a reaction is called the rate-determining step.As a reaction progresses its rate goes down.Reaction rates can show little change as masses of solid reactants increase.

Calculating the reaction rate of one Peactant from that of ano In the Haber reaction, patented by German chemist Fritz Haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. This reaction is now the first step taken to make most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 394. liters per second of dinitrogen are consumed when the reaction is run at 209. °C and the dinitrogen is supplied at 0.45 atm. Calculate the rate at which ammonia is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits. X G 區 ol A 5

(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. As a reaction progresses its rate goes down. The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step. Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities. Reaction rates increase with increasing temperature. Reactions involving very unstable combinations of chemicals have large rate constants.
