### Re: reversing reactions

In a forward reaction, you do products over reactants for the equilibrium equation. For the reverse it is technically reactants over products, so it makes sense that your K would be 1/K for the reverse.

If you reverse the reaction simply take the reciprocal of the the original K value so 1/K.

The value of K in a reverse reaction is the inverse of the forward reaction. If the value of K in a forward reaction is K, then the equilibrium constant in the reverse reaction is 1/K.

The K of the reverse reaction will be the inverse of the K of the forward reaction
Kreverse = 1/Kforward

A + B -> C
Kforward = [C]/[A][B]
Kreverse = [A][B]/[C]

### Re: reversing reactions

When you reverse the reaction, you have to invert K. Therefore, for a forward reaction, the equilibrium constant is equal to K. For the reverse reaction, the equilibrium constant is equal to 1/K.

### Re: reversing reactions

The equilibrium constant (K) for a reverse reaction is simply the inverse of the K for the forward reaction. If you think about it logically it makes sense -- a reaction that heavily favors the products would not have much reactants being formed, and vice versa.

### Re: reversing reactions

For the reaction P <-> R (reversible reaction), [P]/[R] will give us our K value. However, if we reverse what we define as our P and R, we would simply be flipping the equation, so the old R is on top and the old P is on the bottom. This will give us the inverse of our original K value, or simply put, 1/K.

### Re: reversing reactions

K becomes inverted. The way to remember this is that when an equation is reversed, what was once the products (numerator) becomes the reactants (denominator) and vice versa so the K equation would flip.

### Re: reversing reactions

An easy way to calculate the K value for the reverse reaction is to find the reciprocal of the forward reaction, which is K = (1/Forward). I find this calculation quick and simple instead of flipping the formula to K = (R)/(P) and plugging in values from there.

### Re: reversing reactions

Reversing the reaction flips all Reactants to products and vice versa, thus when u are calculating K the top and bottom are flipped which is why we put 1/k when we reverse the reaction.

### Re: reversing reactions

It would be 1/K because in a forward reaction, K = [P]/[R]. In a reverse reaction, the product in the forward reaction would become the reactant in the reverse reaction, and the same goes with the reactant in the forward reaction. Therefore, the K for the reverse reaction equals to [R]/[P]. [R]/[P] is the 1/([P]/[R]). Therefore, it would be 1/K.

### Re: reversing reactions

K is products over reactants so if you use the reverse reaction, K would be the reactants over the products. That's why K (reverse) is 1/K (forward)

The K of the reverse reaction would be the inverse. 1/K or K-1.
EX. [A] + [B] <-> [C]
KFORWARD = [C] / [A][B]
KREVERSE =[A][B] / [C] , which is the reciprocal/inverse of the forward reaction.

### Re: reversing reactions

When you reverse reactions, you are going from products to reactants. Because of that, you would get K = 1/K because K is products over reactants and you would want the reverse, reactants over products because that is the new products/reactants.

Use inverse K (1/k, or K^-1) for a reverse reaction. Think of doing the problem backwards, flip the K.

### Re: reversing reactions

When you reverse a reaction you take the inverse of K, 1/K, because you are essentially just flipping the products and reactants of the reaction. So in the reverse reaction the products are the reactants from the original reaction and the reactants are the products.
