Decomposition of ${\mathrm{N}}_2{\mathrm{O}}_5$ occurs in the following way $2{\mathrm{N}}_2{\mathrm{O}}_5(\mathrm{g})⟶4{\mathrm{NO}}_2(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})$. When ${\mathrm{N}}_2{\mathrm{O}}_5$ is placed in a closed vessel at a certain temperature the pressure of system increases from 100 mm of Hg to 160 mm of Hg in 5 minutes. The rate of disappearance of ${\mathrm{N}}_2{\mathrm{O}}_5$ is
