(wev hint 16 and 20 oe page 6) drained valurs to this variahle. changer 7 Exercise 2 (4 Points): - 15 Minutes Create a function that estimates the rate of a reaction using the following equations: Ea1=12070Ea2=2683r=[k1+k2(1x)]2x10.167(1x)Keq2.2(1x)k1=exp(16.86+TEa1)k2=exp(1.251+TEa2)Kcq=exp(11.22+T11430). Here, r is the output of the function, and temperature (T) and conversion (given by 1x ) are the inputs of the function. Give the name Reaction_Rate to the function and estimate the reaction rate at T=393K for x=0.5. IMPORTANT: Do not delete this MATLAB files, you WILL need it in future labs. Exercise 3 (4 Points): - 30 Minutes Using the Reaction_Rate function created in the previous exercise, estimate the rate of reaction under the conditions described below and plot the results as requested. - Estimate the reaction rate for x=0.5 at T=373K,383K and 393K and show the changes in reaction rate r with respect to temperature T with a plot of r vs T using the plot function (*see Hint 14 on the Hints section on page 5). - Without closing the graph, estimate the reaction rate at the same temperatures as above for an x value of 0.6 and 0.7. Plot these on the same graph as above with different color(s) using plot in conjunction with the hold on command. - Estimate the reaction rate at T=400K and x values of 0.1,0.4,0.5 and 0.9. Then, draw graphs of r vs x and r vs T (based on the data obtained earlier) using the subplot function (see Hint 18 on page 6). - Comment on the impact of changing the temperature on the reaction rate. Can you rationalize these changes ? - Comment on the impact of changing the conversion on the reaction rate. Exercise 4 (2 Points): Use of global variables - 15 Minutes Using the Reaction_Rate function created in exercise 2, estimate the rate of reaction under the conditions defined below using two different values of Ea1 : 10070 and 10000. Plot the estimated results as requested below. (Hint: you will need to run the script twice with different values of Ea1 and use the global function described in hint 19 on page 6). - Estimate the reaction rate for x=0.5 at three different temperatures 373K,383K and 393K, and show the changes in reaction rate r with respect to temperature T with a plot of r vs T. ADD titles to your axis, to your graph, give different colours to each set of data (one colour for Ea1 =10070 and one for Ea1 =10000 ) as well as a legend that specifies the colour, the point and the line type associated with each set of data. (see hint 16 and 20 on page 6 ) 3 Note: you will need to modify the Reaction_rate.m function by defining Ea1 as a global variable (global Ea1). Then, in a similar fashion, define Ea1 as a global variable in your script and assign the desired values to this variable. - Comment on the difference between the two cases. What happens to the reaction rate when Ea1 changes
