The equilibrium position of a certain reversible reaction is unknown. A student mixes the reactants in a test tube and monitors the reaction progress. After one hour, the student claims that the reaction has reached equilibrium. Which of the folkwing onervations would best suurt this
claim?
A) After one hour, the product and reactant concentrations remained constant
B В
After one hour, the product concentration was the same as the reactant concentration,
C After one hour, the reactants were completely consumed, and only products were detected,
D
After one hour, the product concentration began to decrease as reactants were regenerated,
End

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
