Calculate δg°' for the reaction a + b < -> c + d at 25°c when the equilibrium concentrations are [a] = 10 um, [b] = 15 um, [c] = 3 um, and [d] = 5 um. r = 8.314 j/mol⋅k. give your answer to the nearest hundredths in j/mol, but only provide the numerical value (i. e. don't include units in your answer).

The value of ΔG° of the reaction is 5704.82 J/mol.

Explanation:

A + B ⇄ C + D

Equilibrium concentrations of reactants an products:

[A] = 10 μM, [B] = 15 μM, [C] = 3 μM, and [D] = 5 μM

An equilibrium constant of the reaction can be written as:

where,

R = Gas constant =

T = temperature =

= equilibrium constant at 25°C =  0.1

Putting values in above equation, we get:

The value of ΔG° of the reaction is 5704.82 J/mol.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
