The rate constant (k) for a reaction was measured as a function of temperature. A plot of ln k versus 1/T (in K) is linear and has a slope of -7445 K. Calculate the activation energy for the reaction.
Gas a enters the tube, passes through the contents of b, and emerges as gas c. If gas A is a mixture of carbon monoxide and carbon dioxide, and gas c is carbon monoxide, what is the most likely substance in the tube
