To calculate the electromotive potential, also known as potential of the electromotive force (EMF), of a galvanic, or voltaic, cell using the E Cell formula when calculating E Cell: 1. Split the equation into half reactions if it isn't already. 2. Determine which equ...
How do the 3 laws of moition and law of gravitation relate to the law of conservation of energy and momentum? y=kx, calculate the value of k when y = 12 and x = 8. Determine the potential energy of a 25 kg crate that was dragged 1.0 m up a 30 degree ramp. If the coefficient...
• Potential energy transfers to kinetic energy when a rock falls from a ledge. When the rock hits the ground, its kinetic energy is transformed into thermal energy. • In a combustion reaction, chemical energy is transformed into thermal energy. • In reactions that change molecular makeup...
How to Calculate Activation Energy With a Graph Another way to calculate the activation energy of a reaction is to graph ln k (the rate constant) versus 1/T (the inverse of the temperature in Kelvin). The plot will form a straight line expressed by the equation: ...

If we have less of one solution, we expect less heat to be generated. Our final temperature would be lower than expected, and the amount of heat that we calculate would be lower than predicted.Get access to thousands of practice questions and explanations! Create an account Table of ...
To explain the strongncdependence ofτsat lowT, we further analyze theTand chemical potential (μF,c) dependent effective spin-flip ME\overline{| {\widetilde{g}}^{\uparrow \downarrow }{| }^{2}}(averaged aroundμF,c, see Eq. (12)) and scattering density of statesDS(Eq. (15)). ...
ions on each side of a membrane. The Goldman Equation includes other factors like the permeability of the cell membrane and the type of transfer across the surface to calculate this potential. When these cells reach equilibrium then the it's membrane potential is equal to the Nernst potential....
How Much Heat Is Required to Raise the Temperature of a Substance? In order to calculate how much heat is needed to raise the temperature of a given amount of a substance by a given number of degrees you can use the following equation: q=nCΔT Here, q is the heat, n is the number...
