The rate of decomposition of detritus is affected by the abiotic factors like availability of oxygen, pH of soil substratum, temperature, etc. Discuss.

Give an account of factors affecting the rate of decomposition.

Discuss factors which affect oxygen dissociation curve?

Discuss the various factors affecting the rates of chemical reactions.

Radioactive disintegration is a first order reaction and its rate depends only upon the nature of nucleus and does not depend upon external factors like temperature and pressure. The rate of radioactive disintegration (Activity) is represented as -(dN)/(dt)=lambdaN Where lambda= decay constant, N= number of nuclei at time t, N_(0) =intial no. of nuclei. The above equation after integration can be represented as lambda=(2.303)/(t)log((N_(0))/(N)) Calculate the half-life period of a radioactive element which remains only 1//16 of its original amount in 4740 years: a) 1185 years b) 2370 years c) 52.5 years d) none of these

The rate of radioactive disintegration (Activity) is represented as -(dN)/(dt)=lambdaN Where lambda= decay constant, N= number of nuclei at time t, N_(0) =initial no. of nuclei. The above equation after integration can be represented as lambda=(2.303)/(t)log((N_(0))/(N)) Half-life period of U is 2.5xx10^(5) years. In how much time will the amount of U^(237) remaining be only 25% of the original amount ? a) 2.5xx10^(5) year b) 1.25xx10^(5) years c) 5xx10^(5) years d) none of these

Climate refers to the physical environmental factors of an area. These include duration and intesity of light, temperature, humidity, wind, gases, etc. The climate change refers to the changes in these environmental factors of an area over long eriod of time. Main culprit of such climatic change is man himself as his activities are adversely affecting the delicate ecological balance between various components of the environment. Answer the following questions regarding climate change. What are ill-effects of global warming?
