FREE Expert Solution

We are asked what is the new equilibrium equation after multiplying the reaction by a factor of 2.


2A + B ⇌ 4C


multiply by 2: 

(2A + B ⇌ 4C) x 2

4A + 2B ⇌ 8C


Get the Kc expression: 

Kc =productsreactants


The new Kc expression is:

Kc =[C]8[A]4[B]2

Consider the equilibrium reaction 

2A + B ⇌ 4C

After multiplying the reaction by a factor of 2, what is the new equilibrium equation? 

Drag the following labels into the numerator and denominator as needed to create the equilibrium-constant expression, Kc, for the new equilibrium reaction, 

If the initial reaction contains 1.31 M A, 1.21 M B, and 2.51 M C, calculate K0 for the new equilibrium reaction.

Kc =
