I need someone to review my assignment for accuracy and make corrections, as necessary (in another color). I also need assistance answering questions 7 and 10. Please do so as quickly as possible. 1.What factors influence the rate of a chemical reaction?The factors that influence the rate of a chemical reaction are temperature, thenature of the reactants, the concentration of the reactants, and catalysis.2.What is the general form of a rate law?r = k[A]x[B]y[C]z3.What is the order of reaction with respect to A and B for a reaction that obeysthe rate law rate = k[A]x[B]y?2ndorder

Write the rate law for this reaction.r = k[A]2[B]2, where k_ecific rate constant6.If 2 * 10-4moles of S2O82-in 50 mL of solution is consumed in 188 seconds,what is the rate of consumption of S2O82-?(2 * 10-4mol)/(50mL) = 4 * 10-3MThe rate is then: (4 * 10-3M)/(188s) = 2.1 * 1-5M/s7.Why are chemists concerned with the rates of chemical reactions? Whatpossible practical value does this type of information have?8.Suppose you were dissolving a metal such as zinc with hydrochloric acid.How would the particle size of the zinc affect the rate of its dissolution?The smaller the particle size, the faster the dissolution rate and vice versa.The dissolution rate is directly proportional to surface area. 9.Assuming that a chemical reaction doubles in rate for each 10temperature increase, by what factor would the rate increase if thetemperature were increased to 40_?The rate factor would increase by 16 if the temperature were increased to 40_.10. A reaction between the substances A and B has been found to give thefollowing data: 3A + 2B_2C + D[A][B]Rate of appearance of C(mol/L)(mol/L)(mol/L-hr)1.0 * 10-21.00.3 * 10-61.0 * 10-23.08.1 * 10-62.0 * 10-23.03.24 * 10-52.0 * 10-21.01.20 * 10-63.0 * 10-23.07.30 * 10-5Using the above data, determine the order of the reaction with respect to A and B,the rate law and calculate the specific rate constant.
