For the reversible, one-step reaction A+B<>C+D, the forward rate constant is 52.4 /mol*h and the rate constant for the reverse reaction is 32.1 L/mol*h. The activation energy was found to be 35.2 kJ/mol for the forward reaction and 44.0 kJ. mol for the reverse reaction.

a) What is the equilibrium constant for the reaction?

b) is the reaction exothermic or endothermic?

c) What will be the effect of raising the temperature on the rate constants and the equilibrium constant?

Which fact represents evidence for the big bang theory?

Which of your 24 wells had indications that a chemical reaction occurred? how were you able to tell that a chemical reaction occurred? which of your 24 wells had indications that a physical reaction occurred? how were you able to tell that a physical reaction occurred? report on both mixing and evaporation. make a general statement about whether your hypotheses were validated or rejected. must your hypotheses be correct for this to be a successful laboratory?

what is your question? collegechemistry 5+3 pts in november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
