Carbon dating has<span> given archeologists a more accurate method by which they </span>can<span> determine the age of ancient artifacts. The </span>halflife<span> of </span>carbon 14<span> is </span>5730<span> ± 30 </span>years<span>, and the method of dating lies in trying to determine how </span>much carbon 14<span> (</span><span>the radioactive isotope of carbon) is present in the artifact and comparing it to levels</span>
According to the Le-chatelier principle,
the equilibrium constant of an system is affected by following three factors:
1.Concentration of reacting substance
2.Temperature to carryout the reaction
3.Pressure provided during the reaction
