In a typical laboratory setting, a reaction is carried out in a ventilated hood with air circulation provided by outside air. a student noticed that a reaction that gave a high yield of a product in the winter gave a low yield of that same product in the summer, even though his technique did not change and the reagents and concentrations used were identical. what is a plausible explanation for the different yields?
