Methane, a component in natural gas, can be used as a fuel in combustion reactions. what is the value for δgnon (in kj) for the following reaction under the given conditions at 293 k? ch4 (g) + 2 o2 (g) → co2 (g) + 2 h2o (g) where δhorxn = -803 kj, δsorxn = -4.05 j/k, and [ch4] = 14.51 m, [o2] = 9.27 m, [co2] = 3.83 m, and [h2o] = 6.41 m. (in kj)

The for the reaction is -806.86 kJ

Explanation:

We are given:

     (Conversion factor:  1 kJ = 1000)

Temperature of the reaction = 293 K

To calculate the standard Gibbs's free energy of the reaction, we use the equation:

Putting values in above equation, we get:

For the given chemical equation:

The expression for is given as:

We are given:

Putting values in above equation, we get:

To calculate the Gibbs free energy of the reaction, we use the equation:

where,

= Gibbs' free energy of the reaction = ?

= Standard gibbs' free energy change of the reaction = -801813.35 J

R = Gas constant =

T = Temperature = 293 K

= equilibrium constant in terms of concentration = 0.126

Putting values in above equation, we get:

Hence, the for the reaction is -806.86 kJ

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
