Decide with a brief explanation of the following statements about reaction rates and catalysis are true: a) A reaction is the first order of chloride ion concentration. Doubling the chloride ion concentration then doubles the rate of the reaction. b) A unimolecular elemental reaction is always total of the first order. c) The speed law describes how the reaction rate depends on the temperature. d) Catalysis means that the equilibrium constant becomes larger. e) In the Haber-Bosch reaction, a heterogeneous...

REACTION RATES The After Thought 1. Cross out the incorrect statement(s) dealing with factors affecting the rate of a chemical reaction. The rate of a chemical reaction increases: - with increasing concentration of a reactant since the number of collisions increases - with decreasing temperature since the activation energy is reduced - by pulverizing a reacting solid because its exposed surface area increases - with the addition of a...
All of the following statements about the kinetic molecular theory of gases are true EXCEPT: A. The size of the gas molecules is negligible compared to the total volume of the gas B. The average kinetic energy of the molecules of a gas is proportional to the temperature of the gas in kelvins. C. The gas molecules collide with each other and with the surfaces around them. D. Strong attractive forces hold the gas molecules together. E. none of the...
4. -10.1 points 0/4 Submissions Used (a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. Reaction rates decrease with increasing temperature. Catalysts increase reaction rates. O Reaction rates can show little change as masses of solid reactants increase. Catalysts decrease reaction rates. Reaction rates increase as concentrations of homogeneous catalysts increase. Slow reactions can be speeded up by raising the temperature.
All of the following are true about regulons EXCEPT: They can be under positive or negative control. They control operons as well as sets of individual genes that are required to be expressed at the same time. They are present in prokaryotes and eukaryotes. Is how large groups of genes are globally regulated.
