# What is the equation for K equilibrium?

## What is the equation for K equilibrium?

with K=1.34. If the [H2O]=0.100M, [H2]=0.100M, and [CO2]=0.100M at equilibrium, what is the equilibrium concentration of CO?…Equilibrium Constant Expressions.

the decomposition of ozone, O3 | 2O3(g)⇌3O2(g) | Keq=2.0×1057 |

## How do you write an equation for the equilibrium constant?

The equilibrium constant is equal to the rate constant for the forward reaction divided by the rate constant for the reverse reaction….

- K=[N2][O2]1/2[N2O]
- K=[CO2]16[H2O]18[C8H18]2[O2]25.
- K=[HI]2[H2][I2]

**How does Q relate to K?**

Q can be used to determine which direction a reaction will shift to reach equilibrium. If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.

**What is the direction of the reaction if K >> 1?**

A) When K >> 1, the forward reaction is favored and essentially goes to completion. B) When K << 1, the reverse reaction is favored and the forward reaction does not proceed to a great extent.

### How do you find k in a rate law?

To isolate k, you can divide both sides of the equation by 0.000225 M2 to get k = (1.1 * 10-3 M/s)/(0.000225 M2). The units of k become M-1s-1. However, in another (separate, unrelated) example, if the rate law were 4.5 * 10-3 M/s = k[0.034 M]2 [0.048 M]3 , the units for k would be different.

### What is the K constant?

The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s−2⋅C−2.
