At-14.4 °C the concentration equilibrium constant K 5.2x10 for a certain reaction. Here are some facts about the reaction: . The initial rate of the reaction is 14. mol - L .s If the reaction is run at constant pressure, 117. kJ/mol of heat are released. The net change in moles of gases is 2. O Yes Using these facts, can you calculate Kc at 23. °c?

a chemical reaction

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

i believe the answer is 5,000

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.
