A chemical reaction has a positive ΔH value and a positive ΔS value Under what conditions is the reaction spontaneous?
The reaction is spontaneous only at high temperatures.
What is xenon reaction with metals?
Under all but extreme conditions, none.
Why are artifacts stored under airtight temperature controlled conditions?
Artifacts are stored under airtight temperature controlled conditions for many reasons. One is to preserve the current condition it is in.
Under which conditions is the elimination reaction highly favoured?
An elimination reaction is highly favoured if: (a) A bulkier base is used (b) A higher temperature is used. (c) the solvent is ethanol rather than water. (d) a stronger base is used.
Under which conditions does a real gas behave most like an ideal gas?
During low pressure, and low temperature conditions
A chemical reaction has a positive ΔH value and a positive ΔS value Under what conditions is the reaction spontaneous?
The reaction is spontaneous only at high temperatures.
A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
the reaction is always spontaneous :) youre welcome =D i just took this on apex, the correct answer is the reaction is spontaneous only at high temperatures.
Can salt dissolve in water?
Yes, the dissociation of salt in water is a spontaneous reaction under normal conditions.
How can you realise a chemical reaction?
By making interact under certain conditions of temperature, pressure, concentration, etc. the reactants.
What temperature is the reaction at equilibrium?
The temperature will depend on the reaction that is under consideration.
What do standard conditions for a reaction mean?
The standard conditions under which you carry out a reaction are:Carried out at room temperature, 250CA concentration of 1 mol/L for solutions1 atmospheric pressureAll reactants and products must be in physical states that are expected in the above conditions.Standard conditions allow enthalpy changes of different reactions to be compared.
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
What is a substance that enables a chemical reaction to proceed under different conditions?
A catalyst is a substance that enables a chemical reaction to proceed under different conditions. It lowers the activation energy required for the reaction to occur, allowing it to happen more quickly or at a lower temperature or pressure. The catalyst itself remains unchanged in the reaction and can be reused multiple times.
What is the reaction of argon?
Argon is chemically inert and does not have any reaction under normal conditions.
What is xenon reaction with metals?
Under all but extreme conditions, none.
Why are artifacts stored under airtight temperature controlled conditions?
Artifacts are stored under airtight temperature controlled conditions for many reasons. One is to preserve the current condition it is in.
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
