when raymond observes certain natural phenomena, he often forms ideas about their causes and effects. suppose that raymond surmises that
leaves change color in autumn due to scarcity of sunlight. in order to test whether his idea is accurate, he must first construct a falsifiable
that defines a clear relationship between two variables. raymond's next step is to

that
eliminate any
variables that could confuse test results.

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
