ln k2/ln k1 = Ea/R * ((1/T1) - (1/T2)) where R = 8.314 and Temperatures are in Kelvin
The "" symbol in a chemical equation signifies the combination of two or more reactants to form a single product.
You can use the Arrhenius equation to solve for the activation energy barrier (Ea). The formula is k = A * exp(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy barrier, R is the gas constant, and T is the temperature in Kelvin. Since the rate constant triples when the temperature increases from 22.0 to 34.0, you can set up two equations using the Arrhenius equation and solve for Ea.
To determine the activation energy of a chemical reaction using two rate constants, you can use the Arrhenius equation. By plotting the natural logarithm of the rate constants against the reciprocal of the temperature, the activation energy can be calculated from the slope of the resulting line.
An Arrhenius base that contains aluminum is Al(H2O)5OH2+ This ion has the unwieldy name pentaaquadihydroxoaluminum. An Arrhenius base that contains lithium is LiF. This compound is known as lithium fluoride and is basic because F- is the conjugate base of the weak acid HF, and thus will form hydroxide ions in solution.
The balanced equation for the reaction between calcium and chlorine is: 2Ca + Cl2 -> 2CaCl2. This equation shows that two atoms of calcium react with one molecule of chlorine gas to form two molecules of calcium chloride.
Point-slope form is just another way to express a linear equation. It uses two (any two points that fall on the line) and the slope of the line (Therefore the name point-slope form).y2 - y1 = m(x2 - x1)...with m as the slope.
There have been as many Swedish chemists as in other leading countries, but there are two names who stick out the most, historically. Alfred Nobel (not a pure chemist per say, but more of an inventer) and Svante Arrhenius. Svante Arrhenius is most known for the Arrhenius equation, an accomplishment, among others, for which he received the Nobel Prize.
You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.
To find the whole equation of a line, you typically need two key pieces of information: the slope (m) and a point (x₁, y₁) on the line. You can use the point-slope form of a linear equation, which is (y - y₁ = m(x - x₁)). Alternatively, if you know the slope-intercept form, you can write the equation as (y = mx + b) by determining the y-intercept (b) after calculating the slope. Once you have either form, you can rearrange it to standard form if needed.
The equations are equivalent.
Substitute the values for the two variables in the second equation. If the resulting equation is true then the point satisfies the second equation and if not, it does not.
The "form" only refers to how the equation of the line is written. It has no effect on what the line looks like when the equation is graphed. To graph a linear equation, no matter what form it's written in: -- Pick a number for 'x'. Use the equation to calculate 'y'. Graph the point. -- Pick another 'x'. Use the equation to calculate the new 'y'. Graph the point. -- Draw a straight line between the two points, and as much farther as you want to in either or both directions.
The point where two lines form an angle is called the vertex.
To determine the equation of the hypotenuse of triangle RST, you need the coordinates of points R, S, and T. Once you have these coordinates, you can calculate the slope of the line connecting the two points that form the hypotenuse. The equation can then be expressed in the slope-intercept form (y = mx + b) or point-slope form (y - y_1 = m(x - x_1)), where (m) is the slope and ((x_1, y_1)) is a point on the line. Please provide the coordinates of points R, S, and T for a specific equation.
the vertex is the point where two rays begin and form and angle
The standard form of a linear equation is y = mx + bwhere m is the slop of the line, and b is the y intercept.If you have two points (x1,y1) and (x2,y2), you can get the slope with the following formula:m = (y2-y1)/(x2-x1)if you plug this number in to the equation you can then plug in any (x,y) point on the line to solve for b.
To find the equation in point-slope form, we first identify two points from the data: (3, 21) and (5, 35). The slope (m) between these points is calculated as (35 - 21) / (5 - 3) = 7. Using the point (3, 21), the point-slope form of the equation is ( y - 21 = 7(x - 3) ).
