What measures of how fast reaction occurs?
The measure is the rate of reaction.
What are three reasons why enzymes are important?
Enzymes are biological catalysts. They allow the reaction to occur, basically putting together molecules to allow the reaction to happen. They increase the rate of reaction without changing the outcome of the reaction. Increasing the rate of reaction so these reactions can occur fast enough to support life.
What happens to the reaction rate when a catalyst is used in a chemical reaction?
With a catalyst the reaction rate is higher.
What is a property of a reaction that has reached equilibrium?
the rate of the forward reaction is greater than the rate of the reverse reaction.
What is a reaction in a balancing equation?
When an equation is balanced, the rate of the forward reaction equals the rate of the reverse reaction.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
When does a chemical reaction reaches equilibrium?
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
What describes a reaction that reaches equilibrium?
The product and reactants reach a final, unchanging level.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
Could heat increase the rate of reaction?
if reaction is exothermic then on heating rate of reaction wil be low,and if reaction is endothermic then rate of reaction wil be high on heating
What are three ways to increase the rate at which particular reaction proceeds?
There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
Why three fingers are used for checking pulse rate?
of the three fingers the forefinger nd the ring figer are used to occclude the artery nd the middle finger is helpful in measuring the pulse rate
What are three reasons why enzymes are important?
Enzymes are biological catalysts. They allow the reaction to occur, basically putting together molecules to allow the reaction to happen. They increase the rate of reaction without changing the outcome of the reaction. Increasing the rate of reaction so these reactions can occur fast enough to support life.
What is the rate of the of a reaction?
An expression relating the rate of a reaction to the rate constant and the concentrations of the reactants
During dynamic equilibrium how do forward reaction rate and reverse reaction rate compare?
Equilibrium at this point means that the forward reaction and the backward reaction are taking place at the same rate. The formation of the products and the reactants are at equal rate.
What happened to the rate of a reaction as the reaction progresses?
In general, and depending on the order of the reaction, the rate will decrease as the reaction progresses.
