Changes in K

Postby Sydney Pell 2E » Wed Jan 22, 2020 1:16 am

How is K affected when the chemical equation it's based on is multiplied by a factor?

K is basically raised to whatever factor you multiplied your reaction by. Lets say you have 2SO2(g)+O2(g)⇌2SO3(g) and you multiply iy by a factor of 2 obtaining 4SO2(g)+2O2(g)⇌4SO3(g). The K expression is K=[SO3]^4[SO2]^4/[02]^2. For the original equation assume we are given K to be 2.8*10^2, then the K for the new equation will be (2.8*10^2)^2. In short whatever you multiply raise K to that number.

When the reaction is multiplied by a constant, the new K value will be K to the power of that constant.
