1.	`P(g)+2Q(g)toPQ_(2)(g),DeltaH=18kJmol^(-1)` The entropy change of the above reaction `(DeltaS_("system")` is 60 `JK^(-1)mol^(-1))`. At what temperature the reaction becomes spontaneous?A. Below 200 KB. Above 300 KC. Below 300 KD. Above 200 K and below 300 K.
Answer» Correct Answer - B For spontaneous process `DeltaGlt0` `thereforeDeltaH-TDeltaSlt0,DeltaHltTDeltaS` `thereforeTgt(DeltaH)/(DeltaS)=(18000)/(60)=300K`

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example. These bacteria convert atmospheric nitrogen into nitrogenous compound and fix in the soil.The organisms which enrich the nutrient quality of the soil are called(a) Microbes(b) Biofertilizers(c) Yeast(d) Biopesticides
