Which plays a greater role- emotion or reason- during Meursault's trial? Explain in what ways each is employed?

Emotion is what takes over during Meursault's trial. Meursault's existentialist philosophy drives the priest, court, and people watching to emotional extremes. They cannot accept Meursault's rebuke of religion or his general lack of conviction about anything in life. Ironically, his detached demeanor drives other people to frenzied emotion.
