The concentration of potassium ions inside a biological cell is at least twenty times higher than the outside. The resulting potential difference across the cell is important in several processes such as transmission of nerve impulses and maintaining the ion balance. A simple model for such concentration cell involving a metal M is : M_((s)) |M_((aq , 0.05 (" molar"))^(+) ||M_((aq, 1 " molar"))^(+) | M_(s) For the above electrolytic cell the magnitude of the cell potential |E_("cell")|=70mV . For the above cell

Tropospheric pollution is caused by gaseous air pollutants as well as particulate polutants. Among the gaseous air pollutants, oxides of sulphur (SO_(x)) oxides of nitrogen (NO_(x)) and carbon monoxide play an important role towards pollution. Formation of acid rain and photochemical smog. green house effect and global warming all are the result of various chemical and photochemical reactions taking place in the environment. Various particulates including viable and non-viable are also responsible for causing serious air pollution. Which of the following does not contribute towards the formation of photochemical smog ?
