A base is added to water. What happens when the position of equilibrium lies to the left? The base is completely dissociating into products. The base is partially dissociating into products. The base is not dissociating into any ions. The base is present in very small amounts.

first one is the correct answer

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.
