Problem 80

Consider the reaction:

$$2 \mathrm{NO}(g)+\mathrm{O}_{2}(g) \rightleftharpoons 2 \mathrm{NO}_{2}(g)$$

The following data show the equilibrium constant for this reaction measured at several different temperatures. Use the data to find $$\Delta H_{\mathrm{rxn}}^{\circ}$$ and $$\Delta S_{\mathrm{rxn}}^{\circ}$$ for the reaction.

Text Transcription:

2 NO( g) + O2( g) rightleftharpoons 2 NO2( g)

Delta H_rxn^circ

Delta S_rxn^circ

ACIDS AND BASES Acids: produces H+ (which is the same as protons and hydronium ion, H3O+) AND are mostly covalent compounds! H+ + OH- à H2O acid base neutralization The “protics” HCl à H+ Monoprotic ** Compounds that are monoprotic and H2SO 4à 2 H+ Diprotic diprotic are strong acids! H3PO 4à 3 H+ triprotic ** Triprotic are weak acids Ex: H2CO3 à Diprotic weak acid CH 3COOH à monoprotic weak acid Characteristics of acids: Sour Turns blue litmus paper into pink Strong Acids v. Weak acids : 2 converting pH concentration 3 Bases: substances producing OH- in an aqueous solutions AND are ALL ionic compounds Characteristics: Taste is unknown (no one has actually tried it since it is dangerous Turns pink litmus paper into blue Indicators: work in different pH ranges 4 Ex: phenolphthalein detects the pH between 6-8 Bromocresolblue deteacts pH between 3-5 Buffers: Maintain small changes of pH Weak acids/ conjugate bases Weak bases / conjugate acids 5
