Which fator can decrease the rate for chemical reactions . a. low activation energy ,b. hight pressure ,c. low temperature. d.high concentration of reactants

Low temperature will slow the chemical reaction.

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei and can often be described by a chemical equation.

C- Low temperature

When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction.

multiplying and dividing the two decimals and the eqations by the same number of the overalls

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
