Problem 72

The decomposition of NH3 to N2 and H2 was studied on two surfaces: Without a catalyst, the activation energy is 335 kJ/mol. a. Which surface is the better heterogeneous catalyst for the decomposition of NH3? Why? b. How many times faster is the reaction at 298 K on the W surface compared with the reaction with no catalyst present? Assume that the frequency factor A is the same for each reaction. c. The decomposition reaction on the two surfaces obeys a rate law of the form How can you explain the inverse dependence of the rate on the H2 concentration?

Step-by-Step Solution:
Step 1 of 3

CH 101 Chapter 1 notes Law of definite proportions­ ratio of mass and quantity will always be the same Ex. 40 g of CO2 is made up of 12 g of carbon. How much oxygen is present What is the ratio of oxygen to carbon. 40g= total mass 40 g­12 g carbon leaves 28 g oxygen 28 O/ 12 g C = 7:3 John Dalton (1766­1844) Elements are made up of atoms All atoms of an element are the same An atom cannot be created or destroyed Compounds are made of atoms in whole number ratios During a reaction atoms separate and recombine Charges Positive and negative charges (opposite attract), Like charges repel JJ Thomson and the cathode Ray Tube - Glass tube containing metal electrod
