Carbon dating equation with half life
This period of time is called the half-life of the reaction, written as .
If two reactions have the same order, the faster reaction will have a shorter half-life, and the slower reaction will have a longer half-life.
Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.
The two solutions provided differ slightly in their approach in this regard.
Another approach to describing reaction rates is based on the time required for the concentration of a reactant to decrease to one-half its initial value.
In a first-order reaction, every half-life is the same length of time. Calculate the half-life for the hydrolysis reaction under these conditions.
If a freshly prepared solution of cis-platin has a concentration of 0.053 M, what will be the concentration of cis-platin after 5 half-lives? What is the percent completion of the reaction after 5 half-lives? Given: rate constant, initial concentration, and number of half-lives Asked for: half-life, final concentrations, and percent completion Strategy: at 650°C.
