Step 2:Plug in the known values ofE0and n into the Nernst equation to calculate the equilibrium constantKfrom the standard cell potentialE0. Now that we have identified the standard cell potential and the number of moles of electrons transferred, we just need to plug them into ...
It can be made be made by heating sulfur in an atmosphere of methane.For the reaction below, Delta H=760.4kJ/mole of S8 and Delta S=1219.1 J/(K*mole of S8).Calculate the equilibrium constant at 210C and at 440C.4CH4(g) + S8(s) <-> 4CS2(g) + 8H2(g)For the reaction ...
using a ruler. Attach a known weight to the free end and record the new extension. The difference isx. After you calculate the force exerted by the weight, you have your first point (x1,F1). Plot different points by changing the weight and recording the new extension. When you're ...
How to Calculate the pH of a Buffer The Henderson-Hasselbalch equation solves for the pH of a solution using pKa, which is the negative log of the acid dissociation constant. This value is an equilibrium constant for the reaction of {eq}HA \rightleftharpoons A^- + H^+ {/eq}, which ...
Analytical expressions are derived for the analysis of the accuracy of NMR determinations of conformational equilibrium constants, K. The relative error, 蟽K/K, shows a nearly linear increase with K for two commonly used modifications of the NMR approach to conformational analysis (based on ...
Here's a summary of how to calculate the accuracy and precision of your pipette to determine if it needs to be calibrated: Perform the routine check in a draft free environment with a constant temperature between 15 °C and 30 °C
Understand equilibrium constant and reaction quotient and their definitions. Learn their symbols and differences, how to calculate Q and K, and see examples. Related to this Question How does temperature affect equilibrium? What are some ways in which the pressure on an equilibrium system could be...
Calculate the tax muliplier if the MPC is 4/5. If gov't spending ri Evaluate the following statement: "For an economy to be in equilibrium, planned investment spending plus government purchases must equal saving plus net taxes." Explain the effects of the taxes fall by $40 billi...
It's when the body reacts in a physical or emotional way to a challenge or even danger. Stress is a healthy response. And as long as we learn how to manage it, it's fine. It's when we stay in this constant state of stress, also known as fight or flight, that other problems ...
If thevalue for Kcis very large, then the equilibrium favors the reaction to the right, and there are more products than reactants. The reaction may be said to be "complete" or "quantitative." If the value for the equilibrium constant is small, then the equilibrium favors the reaction to...
