WebAnything that changes how effectively molecules collide will affect the speed of the reaction, which is also called the reaction rate. If there are more molecules present, or there’s a bigger surface area on which the reaction happens, there will be more successful collisions and the reaction will go faster. WebAnd because the reaction is first order with respect to each reactant, the initial rate of the reaction would be 5.46 × 10 −12 mol L 1 s 1, which is three times the rate of the initial rate of the reaction in Experiment 1. One point is earned for the correct numerical answer or correct multiplier consistent with the rate law from part (c). sf group jblmWebIf you increase the temperature from 293 K to 303 K (20°C to 30°C), you will increase the collision frequency by a factor of: That's an increase of 1.7% for a 10° rise.
