The slope is proportional to ΔS, which is approximately constant with temperature. The lower the position of a metal's line in the Ellingham diagram, the greater is the stability of its oxide. For example, the line for Al (oxidation of aluminium ) is found to be below that for Fe (formation of Fe
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
Therefore, when the range in temperature is small enough that the standard reaction enthalpy and reaction entropy are essentially constant, a plot of the natural logarithm of the equilibrium constant versus the reciprocal temperature gives a straight line. The slope of the line may be multiplied by the gas constant R to obtain the standard ...
After games in Brazil, the United Kingdom and Germany this season, the NFL plans to keep on growing its international footprint. NFL commissioner Roger Goodell said Sunday that the league is ...
The line with equation ax + by + c = 0 has slope -a/b, so any line perpendicular to it will have slope b/a (the negative reciprocal). Let (m, n) be the point of intersection of the line ax + by + c = 0 and the line perpendicular to it which passes through the point (x 0, y 0). The line through these two points is perpendicular to the original ...
(Reuters) -Alphabet's Google asked a U.S. appeals court on Wednesday to throw out a jury verdict and a judge's order forcing it to revamp its app store Play. In its first detailed argument to the ...
Coffee drinkers may want to think twice before having large doses of caffeine several hours before bed — if they want a good night's sleep. A new study suggests that certain doses of caffeine ...
