Can a rate constant be negative

WebOct 27, 2024 · The exponents m, n, and p are usually positive integers (although it is possible for them to be fractions or negative numbers). The rate constant k and the exponents m, n, and p must be determined experimentally by observing how the rate of a reaction changes as the concentrations of the reactants are changed. WebAug 25, 2024 · Is rate constant negative or positive? Rate constant k should always be positive. From the Arrhenius Equation, we know k = A x exp(-Ea/RT). “A” (frequency factor) will always be positive because (according to Google) there are no experimental cases where A is negative, and mathematically exp(-Ea/RT) can never be negative. ...

http://www.differencebetween.net/science/difference-between-rate-and-rate-constant/ WebWe can, but only for a first order reaction. Each order has its own half-life equation. Zeroth order: ([A0]/2k) First order: (ln(2)/k) Second order: (1/k[A0]) So the zeroth and second order require us to know the rate constant and the initial concentration, while the first order only requires the rate constant. Hope that helps. incomm.com.bn brunei https://goodnessmaker.com
