Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. Predict the effect (shift right, shift left, or no effect) of the indicated volume change.
CO(g) + H2O(g) <=> CO2(g) + H2(g)
PCl3(g) + Cl2(g) <=> PCl5(g)
CaCO3(s)<=> CaO(s) + CO2(g)
What wavelength of light would you report in units of nm, if the light had a wavelength of 7.60 x 10-10 m?
Solving this question helps the student to understand what is happening in a chemical reaction and to balance the given equation.
