As the surface area of the Zn(s) used in the reaction Zn(s) + 2HCl(aq)--> ZnCl2(aq) + H2(g) is increased, the rate of the reaction willIncreaseDecreaseRemain the Same?

An increase in surface area means an increase in the rate of reaction.

What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
Why are nanoparticles more likely to catch fire?
Fire is the chemical reaction of combustion which is the reaction of a substance with oxygen. The rate of the reaction can be increased by providing more surface area for the reaction to occur and nanoparticles have a lot of surface.
How does increased surface area of a reactant in a chemical reaction leads to faster reaction?
The more finely divided the solid is, the faster the reaction happens. A powdered solid will normally produce a faster reaction than if the same mass is present as a single lump. The powdered solid has a greater surface area than the single lump.
Which would react more quickly in a chemical reaction a single sugar cube or an equal mass of graduated sugar crystals?
When the granules dimension of a material is lowered the surface area is increased and the reaction rate is higher.
Why are plasma membranes folded?
Most plasma membranes are the site for important cellular reactions/processes. One of the concepts that crops up all across the field of Biology is the effect of increased surface area and reaction rate. Evolution has driven most vital processes to take place over a large surface area so more reactants can be transformed to products. The folding of a plasma membrane greatly increases its surface area; therefore, reaction rate is increased.
Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on
How might the chewing of food be related to the rate of chemical reaction digestion that occurs in your body?
Chemical reaction rate is increased by: -increased surface area -increased temperature -increased concentration of reactants -presence of a catalyst Chewing food essentially breaks up large chunks of food into smaller bits, increased total surface area for digestion.
What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
What is the relationship between surface area and rate of reaction?
The increase in surface area of reactants increases the contact between reacting molecules, atoms or ions so the rate of reaction becomes increased.
Why is the rate of reaction increased when magnesium is powdered rather than in solid form?
Because more surface area is exposed.
How does surface area of an object affect gravity?
increasing the surface area of reactants in a solid form the speed of reaction is increased the contact between the solid reactants or liquids and gas.
What affects the rate of a reaction?
The rate of a reaction increases if: · The temperature is increased · The concentration of a dissolved reactant is increased · The pressure of a reacting gas is increased · Solid reactants are broken into smaller pieces · A catalyst is used
Why are nanoparticles more likely to catch fire?
Fire is the chemical reaction of combustion which is the reaction of a substance with oxygen. The rate of the reaction can be increased by providing more surface area for the reaction to occur and nanoparticles have a lot of surface.
What is the effect of cutting one single strip of magnesium into more than one when doing a chemical reaction?
The surface area of the magnesium is increased. The reaction will be larger, but normally will take less time.
How do you alter the reaction rate of a chemical change?
Heat - increases it Increased stirring - increases it larger surface area - increases it catalyst - usually increases it and the reverse of the above slows the reaction down
How does increased surface area of a reactant in a chemical reaction leads to faster reaction?
The more finely divided the solid is, the faster the reaction happens. A powdered solid will normally produce a faster reaction than if the same mass is present as a single lump. The powdered solid has a greater surface area than the single lump.
What methods can you use to increase the rate of a chemical reaction?
There are several ways that the rate of reaction may be increased. Some of the more common ways areincrease temperatureincrease surface area (grind or powder the reactants)use a catalystagitate/stir the reaction mixture
