3. (1 pt) Based on your plot for the first set of trials where you kept [HCl] constant and varied [S2O32 ], what is the partial order of the reaction with respect to [S2O32 ]? Explain briefly based on the dependence of the time on [S2O32 ].
4. (1 pt) Based on your plot for the second set of trials where you kept [S2O3 2 ] constant and varied [HCl], what is the partial order of the reaction with respect to [HCl]? Explain briefly based on the dependence of the time on [HCl].

Question 2 0 out of 1 points In an experiment, a student found that the molar mass of NaCl was 57.1g/mol. What is its percent deviation from the literature value?
Response Feedback : The theoretical value is 58.443g/mol. 58.443- 57.1=1.3, with 2 sig figs. The % dev = 100x(1.343/58.443)=2.3%. The value has 2 sig figs from the subtraction, but you need to keep at least one extra digit in the 1.343 term to avoid round-off error. Question 3 0 out of 1 points
Write the mean value and standard deviation for averaging the following 4 values:1.234, 1.345, 1.456, and 1.567
Question 4 0 out of 1 points What is the pH of an HCl solution with a concentration of 0.0135M? Answers:
Response Feedback: There need to be 3 sig figs in the mantissa. The mantissa is the part of the log after the decimal point.
