The decomposition of N2O5 takes place in carbon tetrachloride at room temperature according to the equation, 2 N2O5 (soln) → 2 N2O4 (soln) + O2 (g). The rate constant is 2.35 x 10−4 s−1 at 293.0 K and 9.15 x 10−4 s−1 at 303.0 K. Calculate Ea for this reaction.

What is the cellular process that releases the energy stored in food molecules

Two friends at different locations want to communicate with each other by sending low energy signals. which of the following methods can they use to communicate? a) produce x-rays using colliding electrons and send them to radios, which capture sound b) send messages using infrared radiation, which travel in the form of waves c) send radio waves through intervening media like radio and television d) produce sound waves using microwaves from heated objects

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
