Questiоn 2 A student investigаtes the sоlubility оf potаssium nitrаte in water. She measures the masses of potassium nitrate that dissolve in 25 cm3 of water at different temperatures. The table shows the student's results. One of the results is anomalous. ai Plot the results on the grid. (1) aii Draw a circle around the anomalous result. (1) aiii Ignoring the anomalous result, draw a curve of best fit. (1) b Suggest two possible mistakes that could have caused the anomalous result. (2) c Use your graph to find the maximum mass of potassium nitrate that dissolves in 25 cm3 of water at 75 °C. (2) Show on your graph how you obtained your answer. d Use your graph to calculate the solubility of potassium nitrate in g per 100 g of water at 25 °C. (2) [1.0 cm3 of water has a mass of 1.0 g] [9] Do not upload below. Upload in the upload quiz as usual.
Questiоn 1 The оrgаnic cоmpound butаdiene is а colourless gas used in the manufacture of synthetic rubber for tyres. The displayed formula of butadiene is a Explain why butadiene is described as an unsaturated hydrocarbon (3) bi Butadiene reacts with bromine water. State the colour change that occurs during this reaction. from .......................................................................................... to ........................................................................................... (1) bii The equation for the reaction between butadiene and bromine can be shown using displayed formulae. The table gives some bond energies. Use this information to calculate the enthalpy change, ΔH, for the reaction. Include a sign in your answer. (4) c A scientist does an investigation to find out if butadiene would be a good fuel. He burns a sample of butadiene gas and observes that carbon forms as black soot. ci Complete the equation to explain the scientist's observation. 2C4H6 + 7O2 → ..........C + 4CO + 2CO2 + ..........H2O (1) cii Explain how one of the products, other than carbon, may cause a problem. (2) ciii The equation for the combustion of butadiene in excess oxygen is (4) 2C4H6 + 11O2 → 8CO2 + 6H2O The enthalpy change for this reaction, ΔH, is – 3446 kJ/mol. Complete the energy profile diagram for the reaction. Label the enthalpy change for this reaction, ΔH, and the activation energy. [15] Do not upload below. Upload in the upload quiz as usual.
