Which of the following reactions occurs most rapidly at room temperature?

a.2agno3(aq) + na2cro4(aq) → ag2cro4(s) + 2nano3(aq)

b. cao(s) + 3c(s) → cac2(s) + co(g)

c. sno2(s) + 2co(g) → sn(s) + 2co2(g)

d.2fe(s) + o2(g) → 2feo(s)

The correct option is A.

Looking at the options given above, you will notice that the physical states of the chemical compounds were given in the chemical equations. The reaction in option A is the one that will occur most rapidly because the two reactants involved in the reaction are both in liquid state. Reaction of compounds that are in solid state is comparatively slower because of reduced surface area.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
