Nitrogen monoxide is a pollutant in the lower atmosphere that irriates the eyes and lungs and leads to the formation of acid rain. Nitrogen monoxide forms naturally in atmosphere according to the endothermic 2. reaction: N2(g) + 02 (g) → 2 NO (g) K. = 4.1 * 10-31 Assume that nitrogen composes 78% of air by volume and that oxygen composes 21% of air by volume. Given 1.0 atmospheric pressure, find the "natural" equilibrium concentration of NO in air in units of molecules/cm3. How would you expect this concentration to change in an automobile engine in which combustion is occuring? at 298 K

Hazard Analysis and Design in Chemical Engineering

Hazard is the intrinsic property of a material or process which harms the people, buildings, or environment. Health, safety, hazard, risk assessment, loss prevention, and environmental consideration play an important role while designing a chemical processing plant. Hazard is often confused with risk. Risk measures the magnitude of loss and injury of likelihood incidents or the consequence and frequency of incidents.
