Question

I’m part a what do I put in fx= to execute the function

A chemical reaction is being carried out in a well-stirred tank. The concen- tration of the substance being created can be calculated as a function of time using the formula 59 where C is the concentration in moles per liter and t is the time in seconds. (a) Construct a table of concentration versus time within an Excel work- sheet for the case where a 8 mole/L and b -0.25 sec1 Include individual cells that contain the current values of a and b. Selecta long enough time period so that the concentration approaches its equilibrium value. (b) Create an x-y graph of concentration versus time from the tabulated values. Connect the individual data points with line segments. Add an appropriate title and label the axes. (c) Change the values of a and b to 12 mole/L and 0.5 sec, respectively Notice what happens to the tabulated values and the graph. Note the comparative ease with which these changes are carried out. (d) Restore the original values of a and b. Then alter the type of graph by replacing the arithmetic coordinates with semi-logarithmic coordi- nates. Explain why the resulting graph is not a straight line. Can you rearrange the equation so that it will appear as a straight line when plotted on semi-logarithmic coordinates? (e)
