Dominic and eva are using the same type of stopwatches to measure the time it takes for a chemical reaction to occur. they each use the same stopwatch to measure the time. these are their results:
dominic: 78 seconds
eva: 81 seconds
why are their results unreliable and can lead to a pseudoscientific claim?
they did not repeat their tests multiple times.
they used the same type of stopwatch.
they did not change the reactants in their chemical reactions.
only one person should have collected the data.

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.
