T1 = 650
T2 = 700
K1 = 0.22 1/m.s
K2 = 1.3 1/m.s
R = 8.315 kj/K.mol
I am using equation
ln k2 - ln k1 = Ln k2/k1 = Ea /R [1/T2 - 1/T1]
Since K1 + K2 are in 1/m.s do I have to get the inverse of those figures so that K1 = 4.545 m.s and K2 = .769 m.s?
Second, solving for Ea: Ea/8.315 kj/k.mol * [1/700-1/650]= How do I isolate so that I am solving for Ea?© BrainMass Inc. brainmass.com October 24, 2018, 5:36 pm ad1c9bdddf
K1 and K2 are expressed in 1/ms only. So you don't have to take the inverse.
Let k1 and k2 be the rate constants determined at T1 and T2, respectively. Then you have ...
Let k1 and k2 be the rate constants determined at T1 and T2, respectively. Then you have two equations: ln k1 = lnA - Ea/(R T1) and ln k2 = lnA - Ea/(R T2). From these, you should be able to derive the necessary relationships (answer includes work and calculations).
Using the scientific method for testing the effects of acidic fluid on enzymatic activity
Design and carry out an experiment in which you will test the effects of acidic fluid on enzymatic activity.
1. What question are you asking? Clearly state your hypothesis. Describe your IV and DV.
2. Design your experiment. Provide a detailed account of the materials and methods used to conduct the experiment. Also include the methods for data collection and analysis.
3. Conduct the experiment and record your results. Make a data table that summarizes your findings. You could include what you observed - "which samples showed bubbling?
4. Use your knowledge about enzymes to interpret your results. It may be necessary for you to refer to your textbook. What effect does the acid have on the enzyme?
5. Was your hypothesis supported? What is your conclusion?
