What else can I help you with?
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
How does adding a catalyst to reaction affect it?
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy. It does not change the equilibrium state or the overall thermodynamics of the reaction. This allows the reaction to proceed faster without being consumed in the process.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
What are the features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What is it that undergoes no chemical change during a chemical reaction?
A catalyst does no change chemically.
What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
What are the salient features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
What is a substance that speeds up a chemical reaction but does not change it self?
catalyst
How catalyst can change the rate of a chemical reaction?
speeds it up or starts it
A substance that speeds up a chemical reaction without undergoing a permanent change itself is?
A substance that speeds up a chemical reaction without undergoing a permanent change itself is called a catalyst. Catalysts work by providing an alternative pathway for the reaction to occur, thereby lowering the activation energy needed for the reaction to proceed. Once the reaction is complete, the catalyst remains unchanged and available to facilitate more reactions.
How does adding a catalyst to reaction affect it?
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy. It does not change the equilibrium state or the overall thermodynamics of the reaction. This allows the reaction to proceed faster without being consumed in the process.
