Write the rates for the following reactions in terms of the disappearance of reactants and appearance of products: (a) 302 203 (b) C2H6 C2H4 + H2 (c) Clo- + Br- Bro- + c1- (d) (CH3)3CCI + H20 (CH3)3COH + tt+ + c1- (e) 2AsH3 2As + 3H2

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
