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

Fill in the blanks: Soil, temperature, water and ______ are the key abiotic factors that make life possible.

Assertion: Temperature and soil moisture are the important climatic factors that regulate the process of decomposition. Reason: Warm and moist environment favours decomposition whereas low temperature and anaerobiosis inhibit decomposition.

Given below is a table of factors affecting microbial decomposition ('+' means 'favoring' and'-' means inhibiting or lowering). Select the correct option. A) {:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(+,+,+,-):} B) {:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(+,-,+,-):} C) {:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(-,-,+,-):} D) {:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(-,+,+,-):}

Mention the factors that affect the rate of chemical reaction. For a reaction, the rate law is k[A]^(1//2)[B] . Can this reaction be an elementary reaction? The rate constant for the first-order decomposition of H_(2)O_(2) is given by the following equation log K =14.2 -(1.0 xx 10^(4)K)/(T) Calculate E_(a) for this reaction and rate constant k if its half life period be 200 min.
