Explanation:

'Will be' maybe seen in simple future if the sentence is passive. These apart, 'will' is used to express determination when used with the first person. In British grammar, the command is that ‘will’ should be used with second or third person pronouns like she, he, it, they and you.

‘Be’ is used in past, future and present too. In past, it is used as ‘was’ and ‘were’ and in present, it is used as ‘is’, ‘Am’ and ‘are’; whereas in future it can be used with ‘will’ and ‘be’ is used in passive voices.
