Exercise 6. estimate the k-values and a of a vapour-liquid mixture of water (w) and methane (m) at p = 2 atm, t = 20 and 80°c. what is the effect of t on the component distribution? at these conditions, water exists mainly in the liquid phase and will follow raoult's law. because methane has a critical temperature of -82.5 °c, well below the temperatures of interest, it will exist mainly in the and follow henry's law. table 1: from perry's chemical engineers’ handbook, 6th ed. pp. 3-237 and 3-103 t[°c] 20 pwater (atm) | 0.02307 0.4673 hch. [atm] 3.76.104 6.82 · 104 80

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

he would use the colour black

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.
