Consider the following half reactions: Pt2+ + 2e Pt o = 1.188 V PtCl42 + 2e
Question:
Pt2+ + 2e– → Pt ϐo = 1.188 V
PtCl42– + 2e– → Pt + 4Cl2 ϐo = 0.755 V
NO3- + 4H+ + 3e– → NO + 2H2O ϐo = 0.96 V

I have been teaching college students in various subjects for 9 years now. Besides, I have been tutoring online with several tutoring companies from 2010 to date. The 9 years of experience as a tutor has enabled me to develop multiple tutoring skills and see thousands of students excel in their education and in life after school which gives me much pleasure. I have assisted students in essay writing and in doing academic research and this has helped me be well versed with the various writing styles such as APA, MLA, Chicago/ Turabian, Harvard. I am always ready to handle work at any hour and in any way as students specify. In my tutoring journey, excellence has always been my guiding standard.
