Peroxynitric acid (HOONO2) is an unstable molecule that decomposes to nitric acid and oxygen: 2HOONO2(aq) → 2HNO3(aq) + O2(g)When the concentration of peroxynitic acid is graphed against time, the resulting plot is curved, but if the logarithm of this concentration is plotted, we instead get a straight line. Based on this, which statement is true? a)  This decay is a second order in peroxynitric acid. b)  The slope of the straight-line graph is the rate constant. c)  One needs the concentration of peroxynitric acid to calculate its half-life. d)  The rate law appears to be of the form -Δ[HOONO2]/Δt = k[HOONO2].

Calcium oxide (CaO), an important ingredient in cement, is produced by decomposing calcium carbonate (CaCO3) at high temperature: CaCO3(s) → CaO(s) + CO2(g) In one particular reaction, 40 g of CaCO3 is heated at 450°C in a 5.0 L vessel. The pressure of CO2 is 0.12 atm after 7.0 minutes. What is the average rate of CO2 production in moles per minute during the 7 minutes? (Enter in mol/min.)   If you assume this rate of decomposition remains constant, how many minutes will it take for the entire sample of CaCO3 to decompose?
