Thank you all! I will follow your suggestion and reach out to my instructor for definitive clarification.

Thank you all for your input. How would I go about showing that the function is continuous for all x cannot equal 1? I know that f(x) is defined as a polynomial when x < 1 and a linear function when x > 1 and therefore are continuous everywhere on their domain, but is there a clear way of...

Hello, I recently wrote a test for an introductory calculus class and was confused by the grading of one of the questions regarding continuity. I have attached a screenshot of the test question and my work below. There was a comment reading "Continuity for all x ≠ 1?" and I was deducted marks as...

Thank you for your response. Assuming that the question is asking for the initial concentration of CH3COONa, does the question provide enough information to solve for this? Would I simply use the volume of CH3COONa used instead of the total volume? Concentration of NaCH3COO = 2.5 x 10-3 mol /...

Homework Statement a) Determine the concentration of NaCH3COO. The volume of HCl used to reach the equivalence point is 25.05 mL, the concentration of HCl is 0.10 M, and the volume of NaCH3COO solution used is 10.0 mL. b) Using the initial concentrations of NaCH3COO and HCl, and a reliable...

My true rate equation is R = k [NO]2[O2]. Therefore, the observed rate constant, kobs, is equal to k [NO]2. Rearranging this, I get k = kobs / [NO]2. So do I plug the values from experiment 1 into this equation to get the actual rate constant? k = 0.2328 / [9.63 x 10-1]2 = 0.251 M-2s-1?

Homework Statement Due to formatting problems, I have attached the problem below. Homework EquationsThe Attempt at a Solution Plotting the appropriate graphs and based on linearity, I have determined that the reaction is first order with respect to [O2] and second order with respect to [NO]...

Thank you for your response. Using trials 4 and 2, I have determined that the reaction order is -1 with respect to the hydroxide ion. Therefore, I have determined the reaction to be first order with respect to [OCI-] using trials 2 and 3, for instance. So rate law would be rate = k...

1. Homework Statement Due to formatting problems, I have attached the question below. The attempt at the solution: I am not sure how to deal with the hydroxide ion since it is written above the arrow. I believe that this signifies a species not included in the overall reaction but is...

Pardon me for the incorrect rate law equation that I listed.

1. Homework Statement An iodine clock kinetics experiment was performed by varying the composition of reactant solutions and measuring resulting rates of reaction (based on the data given, I have determined the rate law to be R = [I-]1[S2O82-]1). Which of these four proposed mechanisms below...

Homework Statement Classify the following actions based on how they could affect a reaction rate (rate increases, rate decreases, rate is unaffected) and provide a brief explanation as to why: Add a catalyst Decrease the concentration of a reactant Decrease the surface area of a solid reactant...

Homework Statement Hydrogen peroxide can be prepared in several ways. One method is the reaction between hydrogen and oxygen, another method is the reaction between water and oxygen. Given the ΔG°rxn values for each reaction, which method (reaction 1 or 2) requires less energy under standard...

Homework Statement For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 bar for all species. For the reaction 2 NO(gas) + O2(gas) <---> 2 NO2(gas), the standard change in Gibbs free energy (ΔG°) = -72.6 kJ. What is the ΔG for this reaction at 298 K when the partial...

Homework Statement Hi, To add or subtract sig figs, it is to my understanding that the answer is reported so that it reflects the least precise number. For the example 43.4 - 22 - 3, would I report my answer as 18 or 20? Thanks. Any help is very much appreciated! Homework EquationsThe...
