The trans isomer of [Co(en)2Cl2]Cl complex, and when we add ammonia (NH3) and heat it, it changes the complex to the cis isomer. Any idea as to why?
Although glucose is a more complicated molecule than CO2 and H2O, there is enough entropy in the O2 products to make the reaction generate entropy overall.
