CHEM 001B Lecture Notes - Lecture 19: Reaction Rate, Rate Equation, Reaction Rate Constant
Document Summary
Determine values of n and m by measuring initial rate under different conditions. K can be calculated from the rate law using data for any experiment. Increasing concentration increases collisions between reactants, leading to formation of products. Practice : rate laws/ rate constants the following data: 2no + 2h 2 n 2 + 2h 2 o. Write the rate law and calculate the rate constant k for the reaction given, using. The generic rate law is: rate = k[no] m [h 2 ] n. The actual values for n and m must be determined mathematically from the experimentally observed reaction rate data. Once the reaction orders are determined, data for any trial can be inserted into the rate law to calculate k. Comparing trials 1 and 2, the [h 2 ] doubles while [no] is held constant, and the rate doubles. Comparing trials 1 and 3, the [h 2 ] is constant while the [no] is doubled.
