Q in the nernst equation
WebApr 11, 2024 · Q stands for the reaction quotient Nert Equation Demonstration For the electrode reaction, Nernst demonstrated that: Mn+ (aq) + ne– → M (s) The electrode potential can be represented by any concentration measured in respect of the standard hydrogen electrode: E ( M n + / M) = E M n + / M 0 − R T n F l n [ M] [ M n +] WebSince both ion concentrations are 1.0 molar, Q is equal to 1.0 divided by 1.0 which is one. When we plug all that in to the Nernst equation, we find that the instantaneous voltage is equal to positive 1.10. The second term in the Nernst equation turns out to be equal to zero, because the logarithm of Q is the logarithm of one, which is zero.
