A certain catalyzed reaction is known to have an activation energy E= 11.0 kJ/mol. Furthermore, the rate of this reaction is measured at 296. K and found to be 1.1 x 107 M/s. Use this information to answer the questions in the table below. Suppose the concentrations of all reactants is kept the same, but the temperature is raised by 10% from 296. K to 326. K. How will the rate of the reaction change? Suppose the concentrations of all reactants is kept the same, but the catalyst is removed, which has the effect of raising the activation energy by 5%, from 11.0 kJ/mol to 11.6 kJ/mol. How will the rate of the reaction change? The rate will The rate will choose one choose one choose one stay the same rise about 5% rise more than 5% rise less than 5% fall about 5% fall more than 5% fall less than 5% V

The rate of a certain reaction is given by the following rate law: rate =k[N,]H, ° Use this information to answer the questions below. olo What is the reaction order in N,? x10 Ar What is the reaction order in H,? What is overall reaction order? At a certain concentration of N, and H2, the initial rate of reaction is 0.090 M / s. What would the initial rate of the reaction be if the concentration of N, were doubled? Round M S your answer to 2 significant digits. The rate of the reaction is measured to be 95.0 M / s when [N2] = 0.99 M and [H2] = 1.1 M. Calculate the value of the -2 -1 k = •S rate constant. Round your answer to 2 significant digits.

A student collected conducted 6 kinetics experiments for one reaction by holding the concentrations of ALL the reactants and catalyst constant and varying the temperature. After determining the rate constant for this reaction at the 6 different temperatures, an Arrhenius Plot was made. The graph resulted in a straight line. The equation for the straight line was: y= -4,257.15 x + 14.326 What is the Activation Energy (in Joules/mol) for this reaction at 30 oC? Do not include the units in your answer.

22. The rate of a reaction depends on many factors such as the concentration of the reactants. Which of the following explains why an increase in the concentration of reactants affects the rate of reaction? The reactants move faster. The collisions increase between the reactants. There are fewer molecules present. The activation energy is lowered.
