Determine the transition state for a reaction between the following reactants. Assume the reaction is first order in each reactant. CHCI and NHS MA M O [+] 101 H H HH

Three first-order reactions have the following activation energies: (a) Which reaction is the fastest? (b) Which reaction has the largest half-life? (c) Which reaction has the largest rate?

The following reactions are proposed. Make a rough estimate of the rate of each one rapid, slow, wont react. Explain each answer. a.H2O(l)+H+(aq)H3O+(aq) b.H3O+(aq)+H+(aq)H4O2+(aq) c.3H2(g)+N2(g)2NH3(g) d.Ba2+(aq)+SO42-(aq)BaSO4(s)

Consider the following statements: In general, the rate of a chemical reaction increases a bit at first because it takes a while for the reaction to get warmed up. After that, however, the rate of the reaction decreases because its rate is dependent on the concentrations of the reactants, and these are decreasing. Indicate everything that is correct in these statements, and indicate everything that is incorrect. Correct the incorrect statements and explain.
