A generic gas, X, is placed in a sealed glass jar and decomposes to form gaseous Y and solid Z. 2X(g)−⇀↽−Y(g)+Z(s) How are these equilibrium quantities affected by the initial amount of X(g) placed in the container? Assume constant temperature.

Asample of silver (with work function ? = 4.52 ev) is exposed to an ultraviolet light source (? = 200 nm), which results in the ejection of photoelectrons. what changes will be observed if: silver is replaced with copper (? = 5.10 ev) more photoelectrons ejected no photoelectrons are emitted fewer photoelectrons ejected more energetic photoelectrons (on average) less energetic photoelectrons (on average)
