Consider the reaction below. h2(g) + co2(g) mc013-1.jpg h2o(g) + co(g) at equilibrium at 600 k, the following are true. [co2] = 9.5 x 10-4 m [h2] = 4.5 x 10-2 m [h2o] = 4.6 x 10-3 m [co] = 4.6 x 10-3 m what is the value of the equilibrium constant for this reaction in correct scientific notation? 4.9 x 10-3 4.9 x 10-2 4.9 x 10-1 4.9 x 103

Ans: c) 4.9 *10-1

Given:

Concentrations of the reactants and products-

[CO2] = 9.5 x 10-4 M

[H2] = 4.5 x 10-2 M

[H2O] = 4.6 x 10-3 M

[CO] = 4.6 x 10-3 M

To determine:

The equilibrium constant K

Explanation:

The given reaction is:

H2(g) + CO2(g) ↔ H2O(g) + CO(g)

The equilibrium constant is given as:

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
