What else can I help you with?
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
Is copper a catalyst?
yeap, a heat catalyst
How can activation energy be reduced?
Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of reaction.
What do you call a substance that accelerates the rate of a chemica reaction?
A substance that accelerates the rate of a chemical reaction is called a catalyst.
Why is an example of a heterogeneous catalyst?
catalysts which are in the same phase to that of reactants and products

What are examples of anti-catalyst substances?
they are inhibitors of chemical reactions or diminishes the activity of a catalyst. The inhibition is temporary when the poison is adsorbed on the surface of the catalyst in preference to the reactants. The Permanent poisoning is when a covalent bond is formed between the poison and the catalyst.for example volatile sulfur and volatile silicon cause permanent poisoning during many cases. Arsenic are poison to platinum. In the reaction of decomposition of H2O2 by platinum, HCN act as poison. In another case CO act as poison to copper during the reaction of hydrogen and ethylene.
Which does a catalyst not change?
Catalyst is not a reactant.
Catalyst vs one without catalyst What is different?
what is the purpose of catalyst in textile paint?
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.

What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.
When was Catalyst - magazine - created?
Catalyst - magazine - was created in 1944.
