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...
Using Hess's law, calculate Delta H value for the following reaction: Fe_2O_3 (s) + 3CO (g) to 2Fe (s) + 3CO_2 (g) Using Hess's Law and some or all of the equations (1) - (4) below calculate \Delta H^\circ \text{ at } 25^\circ C for the react...
Because the rate of these decomposition reactions can be measured, the concentration of any radioactive isotope can be calculated at any time. The constant that is usually used in these calculations is the half-life, which it the time needed for one half of an original to decay. Half-life ...

How do you calculate enthalpy change for a product of reaction? Calculate the standard enthalpy change for the reaction at 25 ^oC. Mg(OH)2(s) + 2HCl(g) \rightarrow MgCl2(s) + 2H2O(g) Determine the standard enthalpy change for the reaction b...
Now that we have established the Nernst equation we can find out what it actually tells us. The key value here is the reaction quotient Q. The cell potential during an oxidation-reduction reaction is closely related to the Gibbs Free Energy equation (often called delta G) which describes how...
We use data on fatal crashes to quantify the risk of distracted driving. We repurpose, extend, and improve a methodology used to estimate the riskiness of
E-mini S&P 500 futures have been traded for more than two decades and represent one-fifth of the value of the SPX. A "multiplier" is used to calculate the notional value of a contract, which is $50 times the price of the SPX for the e-mini contract. ...
How to calculate enthalpy change Enthalpy Change:Enthalpy change is a measure of the amount of energy released or absorbed during a chemical reaction. A negative enthalpy change indicates that heat was released (known as an exothermic reaction), while a positive enthalpy change indicates that heat ...
