In order to calculate this experimentally you have to monitor either the concentration of the reactant or product as a function of time. Once you have measurements at different times you can then plot these values and find the instantaneous rate of the reaction or the slope of the line. Pret...
Calculation of Enthalpy of Reaction Example 1: Calculate the temperature change that results from adding 250 J of thermal energy to 0.50 moles of mercury. Visualize the diagram of the Heat System and Surroundings with the arrow direction going into the system. Use the formula: _q = nCmΔT_ ...
The reaction quotient is valid atall times, so the reaction doesn't have to be at equilibrium for you to calculate it. However, when the reaction is at equilibrium,Q=K,and the two equations give the same result. Calculate Q for a Reaction The equation forQ, for a general reaction betwe...
the equilibrium constant Kc is defined as [AB]/[A][B]. Brackets denote reagent concentrations that must be given in order to compute Kc. As an example, we will calculate Kc for two reactions. The first is the
How can one determine the rate determining step of a chemical equation, and how is it different from the rate law?Answer and Explanation: Hello, To determine the rate determining step, you need to determine the rate of each step of the reaction. ...
How is the rate of a chemical reaction expressed? What is the yield and purity of the synthesis of ammonia through the Haber process? Evaluate and provide reasons to support the judgement. What can change the rate of a reaction? How to calculate the amount of enzyme(ng) in rea...
Re: How to calculate the number of moles of Fe2+ produced in the reaction? « Reply #3 on: October 11, 2009, 09:37:05 AM » Sorry about the equation. it was supposed to be 5Fe2+ (aq) + MnO4- Mn2+ + 4H2O (l) + 5Fe3+ (aq) Typo error. Quote No, you have it reverse...
Clearly there’s a cost to responding to feedback. Everyone’s natural reaction is that they’re far too busy already and they can’t possibly respond to feedback. But that’s falling into the trap of looking at only one side of the cost/benefit equation, because there’s a cost in ...
How to Calculate Normality of a Chemical Solution Normalityis similar to molarity, except it expresses the number of active grams of a solute per liter of solution. This is the gram equivalent weight of solute per liter of solution. Normalityis often used in acid-base reactions or when dealing...
of ions on each side of a membrane. The Goldman Equation includes other factors like the permeability of the cell membrane and the type of transfer across the surface to calculate this potential. When these cells reach equilibrium then the it's membrane potential is equal to the Nernst ...
