Question

luminol is a compound that can undergo a chemiluminesence reaction with peroxide and catalyst to give blue light. In the daylight it is hard to see this light, though. However, glowsticks are glowing so much that they are also visible in the daylight. And in the glowsticks, some chemical dyes are necessary to use where in case of luminol, it is not. Explain the difference of luminol and glowsitcks in terms of both the strength of light and also necessity of dyes

Answer 1

Glow sticks produce light and its intensity depends on the temperature. Higher is the temperature, higher will be the intensity. So a glow stick placed in freezer emits almost no light, when compared to glow stick at normal temperatures. The dyes absorb light from the reactions and emit them to produce colors. While the strength of light by luminol is not so high, as the color fades away quickly.

Answer 2

For glow sticks the reactions are temperature-dependent. Here the reaction become faster with increase in temperature and produce a fantastic glow, but it will not last as long as it would at room temperature. Because at low temperature the reaction rate slows down and long after it would have stopped glowing. luminol is a compound that can undergo a chemiluminesence reaction with peroxide and catalyst to give blue light. In the daylight it is hard to see this light, though. It is not temperature dependent reaction.
