If a change in conditions causes the equilibrium constant, $K_{eq}$, to increase, what effect does that have on the free-energy change ($\Delta G°$)? It could increase or decrease $\Delta G°$, depending on the specific reaction. It does not affect $\Delta G°$. It increases $\Delta G°$. It decreases $\Delta G°$.

The team monitoring a space probe exploring the outer solar system finds that radio transmissions from the probe take 2.58 hours to reach earth. How distant (in meters) is the probe? m In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. The distance to Alpha Centauri, the closest star other than our own sun that can be seen by the naked eye, is about 4.1 light-years. Express this distance in meters. m A truck driver is broadcasting at a frequency of 27.405 MHz with a CB (citizen's band) radio. Determine the wavelength of the electromagnetic wave being used. The speed of light is $c = 2.9979 \times 10^8$ m/s. m
