A more thorough explanation:

A dissolving condition is a type of resolutory condition. It means that a contract or agreement will be terminated or dissolved if a certain condition is met.

John and Jane sign a lease agreement for an apartment. The agreement includes a dissolving condition that states the lease will be terminated if the apartment building is destroyed by a natural disaster. A few months later, a tornado hits the building and destroys it. The dissolving condition is met, and the lease agreement is terminated.

In this example, the dissolving condition is the destruction of the apartment building by a natural disaster. Once this condition is met, the lease agreement is dissolved.

To dissuade means to persuade someone not to do something.

Tom wants to drop out of school, but his parents try to dissuade him by explaining the importance of education and the negative consequences of not having a degree.

In this example, Tom's parents are trying to dissuade him from dropping out of school by persuading him to continue his education.
