Related to this Question How do you calculate the half-life of a first-order reaction? The rate constant, k, for a first-order reaction is equal to 4.3 x 10-4 s-1. What is the half-life for the reaction? a. 1.2 x 103 s b. 1.6 x 103 s c. 2.4 x 103 s d. 3.0 x 10-4...
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...
Potential energy transfers to kinetic energy when a rock falls from a ledge. When the rock hits the ground, its kinetic energy is transformed into thermal energy. In a combustion reaction, chemical energy is transformed into thermal energy. In reactions that change molecular makeup, energy is ei...
In chemical kinetics, the concept of half-life is associated with the time necessary for the initial amount of sample to be one-half its original amount. A first-order chemical reaction relates the half-life to its rate constant k. The relationship is given...

MPC is calculated as the ratio of marginal consumption to marginal income. MPC is related to the so-calledKeynesian multiplier, where MPC can help predict the economic growth from a government stimulus. The multiplier effect refers to a chain reaction of consumption by various entities brought abou...
Chemists use titration as a method of quantitative analysis; that is, the method allows the exact quantity of a compound to be determined. Fundamentally, titration involves the combination of two chemicals that react and a means of monitoring the progress of the reaction so that the operator know...
