Why the reactions of high order are rare?
The reactions of high order are rare because order of reaction cannot be greater than three, however it may be in minus or fractionHigher order means that n>3, that is why reaction of higher order are rare.
What order are redox reactions balanced?
Atoms, O and H, then charge
What is an another name for exothermic and for endothermic reactions?
it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).
What are exothermic and endothemic reaction?
And endothermic (if that's what you meant) reaction is one that requires heat to proceed. The system absorbs the heat in order to progress.We show no listings for "endothemic" though.
How many atom of a 1.0 mole sample of bismuth 214 will remain after 20 minutes?
All radio active reactions are of first order reactions , for those first order reactions rate constant , k = 0.693 / t 1/2 : t 1/2 = half life of Bi is = 19.7 min So k = 0.693 / 19.7 = 0.0352 min -1 For a first order reaction rate constant , K = ( 2.303/t)x log (a / ( a-x) ) Where a = initial atoms = 6.023x10 23 atom / mol a-x = atoms left after time t = ? t = time = 20 min Plug the values we get log (a / ( a-x) = kt / 2.303 = ( 0.0352x20 ) / 2.303 = 0.305 a / (a-x) = 10 0.305 = 2.02 (a-x) = (6.023x10 23 ) / 2.02 = 2.98 x 10 23 atoms
How does post traumatic stress disorder differ from combat operational stress reactions?
PTSD has specific chronological requirements and symptom markers that must be satisfied in order to diagnose

Why the reactions of high order are rare?
The reactions of high order are rare because order of reaction cannot be greater than three, however it may be in minus or fractionHigher order means that n>3, that is why reaction of higher order are rare.
What is the two sets of reactions that need to occur in order for photosynthesis to take pace?
light dependent and light independent reactions
When is a reaction said to be endothermic?
The chemical reactions that must absorb energy in order to proceed. These are endothermic reactions.
What is an apparent rate constant?
First order rate constant k is described in V=k[EA] while second order rate constant is given as V=k[E][A]. For reactions that do not have true order, k is the apparent rate constant.
Whether order and molecularity be equal in any case?
for every elementary reactions, order and molecularity are equal
What order are redox reactions balanced?
Atoms, O and H, then charge
Do catalyst produce chemical reactions?
yes chemical reactions in order to induce a chemical reaction that might normally take a long time
What does cells require in order for chemical reactions to take place?
enzymes
