Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
Reaction rate refers to how quickly or slowly the?
speed of reaction
Do enzymes speed up metabolic reaction in organisms?
Yes,enzymes speed up metabolic reaction in organisms.
What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
It can be done with those substance which remains as it was before the reaction but increases the speed of the reaction.
Is it that reaction distance increases with speed while the reaction time stays the same?
Yes, the reaction distances increases with speed while reaction time stays the same. for example the two-second rule.
What is meant by the rate of reaction?
The how much speed it takes for two substances to make one product. Many factors can affect this including the temperature, the surface area, the concentration, the catalyst and the pressure (only applies for gases)
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.
What is a reaction rate apex?
how slow or fast A reaction progresses - apex
Why does the reaction decrease as the reaction progresses?
There are fewer reactants left to collide.
What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
What causes the reaction rate to decreases as the reaction progresses?
The concentration of the reactants decreases.
What happens to the rate of reaction as the reaction progresses?
The rate decreases as reactants are used up.
How is the speed of chemical reaction related to the spontaneity of the reaction?
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
Why does the rate of a reaction speed up?
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.
How is reaction time different to speed?
Reaction time is a noun. Speed is a hard drug.
What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
When zinc is reacting with hydrochloric acid what make the reaction start slowly and speed up in a few minute?
The acid first has to dissolve away the zinc oxide layer that coats the zinc as more metal gets exposed the acid can react with the exposed metal. Also as the reaction progresses the solution heats up which also speeds the reaction.
