Lowers the activation energy of a reaction, therefore speeding the reaction up.
Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
For a healthy adult: heart rate of 60-100 beats/minute, respiratory rate of 12-20 breaths/minute
Benadryl has the potential speed up your heart rate as an adverse reaction, specifically palpitations. This drug should be used with caution in patients with Heart Disease and/or High Blood Pressure. This is because the cardiovascular adverse effects can be serious to those people with these conditions. These effects include a change in blood pressure, palpitations, and tightness in the chest.
Alarm reaction phase
60-100 is the normal heart rate for an adult, but it varies per person. If your heart rate is normally around 90, a heart rate of 60 is going to be abnormally low. Also, many factors can cause a change in your heart rate, such as a change in body temperature, pain, exercise, nervousness, etc.
Polar makes the Bluetooth Polar Stride Sensor which is a popular heart rate monitor with a clip and easy to change batteries. Panobike also has a line of heart rate monitors as well.
A catalyst alters the rate of a chemical reaction.
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
speeds it up or starts it
A catalyst doesn't undergo a chemical change during a chemical reaction.
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
When a catalyst is added to a chemical reaction, the rate of the reaction will increase without being consumed in the process. This means that the reaction will reach equilibrium faster and require less activation energy. The overall chemical equilibrium and products formed will remain the same.
The process is spelled catalysis (change in reaction rate).The substance that makes a chemical reaction change is a catalyst.
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.
A catalyst is not consumed in a chemical reaction, meaning it does not undergo a permanent change in its own chemical structure. It increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy.
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
