What describes the energy of activation?
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
How does a catalyst increase the rate of a chemical reation?
A catalyst decreases the threshold energy value with which two particles must collide in order to react.
Reactants and products in an energy diagram?
Activation energy is the distance from the reactants to the top of the "hill."
What is the energy profile of a chemical reaction including activation energy free energy change and transition state?
These are all pictured here, it is describing the energy state for a reaction. http://images.absoluteastronomy.com/images/encyclopediaimages/a/acactivation_energy.svg.png Free energy refers to the Gibbs energy for a reaction, this is what tells us if the reaction will take place. It is defined as the difference of energy (y-axis) between the initial and final. In order for the reaction to be spontaneous, the final energy state must be lower than the initial. Activation energy is the amount of energy that must be introduced into the system in order to begin the activation. On the graph, it is the peak. The graph does not have any transition species, but if did they would be denoted by other "hills" in the curve, between the activation and final states.
Explain the communication process of neurons in the brain?
When transmitting a message, a signal travels through the neuron until the cell ends at the terminal. In order to propagate the signal to the next neuron chemical messengers (neurotransmitters) are released into the inter-neuronal space (synapse). This triggers signal initiation in the second neuron.
What is game maker activation code?
A game maker activation code is when you order a CD with a code on the back
The amount of energy which a system has to have in order for a chemical change to take place?
The activation energy.
What is a sentence using the word activation energy?
Activation Energy is the required energy needed in order for a chemical reaction to start.
What term is used to describe the minimum amount of energy required in order for a reaction to proceed?
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
Does your cell phone have to be off in order for it to be activated?
Yes, your cell phone has to be on in order for them to send the activation through satillite and the phone sends it back to the satilitte so they can see on their side that you received the activation on your cell phone
What is the correct order of events for hormones activating Gs proteins?
activation of G protein, binding of GTP, activation of adenylate cyclase, conversion of ATP to cAMP
Which is the correct order of events for hormones activating Gs proteins?
Activation of G protein, binding of GTP, activation of adenylate cyclase, conversion of ATP to cAMP
What is the McDougal Littell World History online textbook activation code?
You have to purchase an online or print edition of the book in order to receive an activation code.
What describes the energy of activation?
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
Is Activation energy the minimum energy needed for a reaction to start?
No, the opposite. The lower the activation barrier the faster the reaction goes. That is how a catalyst speeds up the reaction: by lowering the activation energy.See the Web Links for more information.
Use an Arrhenius plot to determine the activation barrier for the reaction?
You have to have data in order to find Ea.
What is the amount of energy which a system has to have in order for a chemical change to take place?
That is officially called the activation energy.
