6. What is the equilibrium constant for the following reaction?<br> C+02 = CO2
Orlov [11]
<h3>\tt Kc=\dfrac{[CO_2]}{[C][O_2]}</h3><h3>Further explanation</h3>

Given

Reaction

C+02 = CO2

Required

The equilibrium constant

Solution

The equilibrium constant is the ratio of concentration or pressure between the product and the reactant with each reaction coefficient raised  

The equilibrium constant is based on the concentration (Kc) in a reaction  

pA + qB -----> mC + nD  

\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}

So for the reaction :

C+O₂ ⇔ CO₂

\tt Kc=\dfrac{[CO_2]}{[C][O_2]}

What are the two variables that affect the electric force between two objects?
givi [52]

Explanation:

The electrical force between two objects is given by the formula as follows :

F=\dfrac{kq_1q_2}{d^2}

k is electrostatic constant

q₁ and q₂ are electric charges

d is distance between charges

So, the two force between two charged objects depends on the product of charges and distance between charges.
