If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?
It doesn't - the reaction rate will not change regardless of how much of that reactant is added. That's the definition of zero-order.
How does an increase in surface area affect the rate of weathering?
If you do a chalk experiment, you will find out that increasing the surface area speeds the rate of weathering. The reaction/weathering will happen quicker. Most people are doing this in science. Your welcome
How does an inhibitor affect the rate of chemical reaction?
Enzymes fasten chemical reactions, inhibitors blocks the enzymes and they will not accelerate the reaction.
What is the most important factor that affects the rate of weathering?
climate
How does NaCl affect the rate at which amylase hydrolyse starch?
It speeds up the reaction so amylase works faster.
How does the factor concentration affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
State one other factor apart from temperature that will affect the rate of reaction of amylase?
pH and temperature
How does heat affect the rate of the reaction?
Increasing the temperature the reaction rate increase.
How does changing the temperature of solutions affect the rate of reactions?
In most cases, increasing the temperature increases the rate of the reaction.
A factor which influences the reaction rate?
Concentration of reactants is one of the factors influencing the reaction rate. More the concentration, more will be the reaction rate.
A factor that affects the rate of reaction?
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
Which factor affects the reaction rate by altering the reaction path?
catalyst
How does concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
How does the present of a catalyst affect the rate of reactions?
A catalyst is a substance which speeds up the rate of reaction. After the reaction it remain chemically unchanged. It does NOT affect the position of equilibrium. There can also be negative or "poisoned" catalysts as in Rosenmunds reaction.
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
When would pressure affect the reaction rate?
if gases are involved in the reaction.
Does concentration have an affect on reaction rate?
Yes.why
