What equation is used to calculate the free energy change a reaction?
Delta G (written triangle G) = Delta H -T Delta S
What does the delta h of a reaction represent?
Either the change (which the delta refers to) of the height (which the h represents).
How to calculate delta temperature?
To calculate the delta temperature, you will take the difference between the final and initial temperature.
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 delta h in the equation delta g delta h - t delta?
The change in enthalpy between products and reactants in a reaction
What is the formula for heat supplied to a chemical reaction?
calculate heat of reaction u ll get the idea ....how much heat need to supply for reaction

When is heat of a reaction equal to the enthalpy change of the same reaction?
I'm pretty sure its when the pressure remains constant. When the pressure is constant: q=delta U + P delta V The equation for delta H is: delta H = delta U +P delta V Therefore, when pressure is constant: delta H = q I think...
Calculate delta G at 298K for the reaction of nitrogen and hydrogen to form ammonia of the delta G equals -33.3kJn and the reaction mixture consists of the follwing N2.5 atms H2.75 NH3 2.0?
you have to show that school is gay af
If you have the heat of formation of a substance at a given temperature how do you calculate its heat of formation at a different temperature?
Say u know heat of formation at temperature Ta and u want to calculate it at a temperature Tb Delta H(at Tb) = Delta H(at Ta) + integral of (Heat capacity) from Ta to Tb
What does the delta h of a reaction represent?
Either the change (which the delta refers to) of the height (which the h represents).
When a chemical reaction has a negative delta G is the reaction exothermic or endothermic?
When a chemical reaction has a negative delta G, the reaction is exothermic because delta G is the change in energy of a system and the change in its entropy. If the effect of a reaction is to reduce G, the process will be spontaneous so delta G is negative. Hope this helps :)
How to calculate delta temperature?
To calculate the delta temperature, you will take the difference between the final and initial temperature.
Calculate the change in enthalpy for the Mg HCl reaction using standard enthalpies of formation delta hf for HCl aq equals -167.2 kj and delta hf for MgCl2 aq equals -791.2 kj?
-1282.5J
How do you calculate delta t?
To calculate Delta t, you would subtract Universal Time or UT from Terrestrial Time or TT. Delta t would be the difference.
