In methane combustion, the following reaction pair is important: At 1500 K, the equilibrium constant Kp has a value of 0.003691
andre [41]

Explanation:

Let us assume that the value of K_{r} = 2.82 \times 10^{5} \times e^({\frac{-9835}{T}}) m^{6}/mol^{2}s

Also at 1500 K, K_{r} = 2.82 \times 10^{5} \times e^({\frac{-9835}{1500}}) m^{6}/mol^{2}s

                     K_{r} = 400.613 m^{6}/mol^{2}s

Relation between K_{p} and K_{c} is as follows.

                  K_{p} = K_{c}RT

Putting the given values into the above formula as follows.

                  K_{p} = K_{c}RT

         0.003691 = K_{c} \times 8.314 \times 1500

                K_{c} = 2.9 \times 10^{-7}

Also,     K_{c} = \frac{K_{f}}{K_{r}}

or,                K_{f} = K_{c} \times K_{r}

                               = 2.9 \times 10^{-7} \times 400.613

                               = 1.1617 \times 10^{-4} m^{6}/mol^{2}s

Thus, we can conclude that the value of K_{f} is 1.1617 \times 10^{-4} m^{6}/mol^{2}s.

What occurs along a convergent plate boundary ?
Margaret [11]

Answer:

Two plates pull towards each other

Explanation:

Along a convergent plate boundary, two plates moves towards each other as the move in the same direction.

This results in different forms of plate interactions depending on the plate types.

  • At an ocean - ocean and continental - ocean convergent front, subduction of the oceanic plate occurs. This is because the oceanic plate below is denser than the asthenosphere.
  • At a continental - continental convergent front, the continental crust is pulls upward and build up as a mountain.
  • The subduction produces trenches and some volcanic islands.

3) The total number of orbital’s in a shell with principle quantum no (n) is​
melamori03 [73]

Answer:

nine

There are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell. The n = 3 shell, however, also includes 3d orbitals. The five different orientations of orbitals in the 3d subshell are shown in the figure below.

1. Why don't scientists stop with the first step in the Scientific Method, making observations? A. They don't trust their own ob
natulia [17]

Answer:

Explanation:

Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.

                     OR

Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them    

       

Hope any one of these helps you
