a. graph C, vs T then using excel what polynomial trendline is needed to get a fit of R? = 0.999? Using this polynomial what would be the heat of a process heating 3.189 mol of nitrogen gas from 461 K to 917 K? b. Fit the data above using what many texts do: Cy = A + BT +C/T?. This is something likely to be new to you using excel. You will have to have a column for Tand an adjacent column for 1/T?. Then a column for Cy. Go into Data analysis under tools and choose regression. Enter in your Cy column for y and select BOTH the T and 1/T2 columns for your x values. Choose a square in your excel sheet to place the answers. The A, B and C values will be in there! What would the heat of the process from part a be now if using this C(T)?
