Transcription of this question: 3.26g of iron powder are added to 80.0cm3 of 0.200moldm-3 copper(ll) sulfate solution. Thefollowing reaction occurs:(a)0)(ii)Fe(s) + CuS04(aq) Feso, (aq) + cu(s)Determine the limiting reactant showing your working.The mass of copper obtained experimentally was 0.872 g.percentage yield of copper.Calculate the[2][2]0)The reaction was carried out in a calorimeter. The maximum temperature rise ofthe solution was 7.50C.Calculate the enthalpy change, AH, of the reaction, in kJ, assuming that allthe heat released was absorbed by the solution. Use sections 1 and 2 of thedata booklet.[2](c)(ii)(iii)0)State another assumption you made in (b)(i).The only significant uncertainty is in the temperature measurement.Determine the absolute uncertainty in the calculated value of AH if the uncertainty inthe temperature rise was ±O.20C.Sketch a graph of the concentration of iron(ll) sulfate, FeS04, against time as thereaction proceeds.[2][2]Time(ii)(iii)Outline how the initial rate of reaction can be determined from the graph inpart (c)(i).Explain, using the collision theory, why replacing the iron powder with a piece ofiron of the same mass slows down the rate of the reaction.[2][2]
