Please hellp answer two attached questions ASAP. Thanks.
Please zoom in to see pics
1. Consider this 1-D lattice (the lattice can repeat only to the left and right of the figure). This lattice is made up of large atoms and small atoms. The bonds between two large atoms have a well depth of e1. The bond between a large atom and a small atom have a well depth of e2. Bonds do not form between two small atoms.
You are given this substance with 2 moles of large atoms in it, what is its bong energy?
2. A 14 atom solid begins in a 2D lattice shown below. The well depth for each bond is epsilon. The lattice was happily sitting in a lab until robots from the future appeared and used their HEAT vison. The solid started going through a phase change until it became the final state on the right. How much heat did the robot give this substance (be clear with the sign)?
