How does temperature affect the spontaneity of a reaction? A. Increasing the temperature always makes a reaction less likely to
be spontaneous
B. Increasing the temperature will not affect the spontaneity of a
reaction.
C. Increasing the temperature always makes a reaction more likely to
be spontaneous.
D. Increasing the temperature makes a reaction spontaneous in
some situations.

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.

As we move from left to right across the periodic table, what is the general trend? a) atomic radii increase. b) electronegavitiy decreases. c) nuclear shielding increases. d) metallic character decreases.

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
