WebUsually reactions speed up with increasing temperature ("100C rise doubles rate"). Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor). WebFeb 12, 2024 · N O 2 + C O → k N O + C O 2. rate = k [ N O 2] 2 (observed) The experimentally determined rate law for the reaction of N O 2 with C O is the same as the predicted rate law for step 1. This tells us that the first elementary reaction is the rate-determining step, so k for the overall reaction must equal k 1. someone out there 意味
