The decomposition of dinitrogen pentoxide is described by the chemical equation
2 N₂O₅(g) → 4 NO₂(g) + O₂(g) .
If the rate of appearance of NO₂ is equal to 0.560 mol min^-1 at a particular moment,what is the rate of appearance of O₂ at that moment?

The rate of appearance of $NO_2$ is 0.560 mol/min, and since the stoichiometry of $NO_2$ to $O_2$ in the reaction is 4:1, the rate of appearance of $O_2$ is one fourth of that of $NO_2$, which is $0.560 \, \text{mol/min} \div 4 = 0.140 \, \text{mol/min}$.
