- Formula equation for the reaction of Iron (II) with Copper (II) Sulphate:
- to lower their potential energy and because of the differende in potential energy between the anode and cathode
- Apparent first order rate constant, kobs
- What sort of graph is a 1st order conc vs time?
- What sort of graph is a zero order conc vs time?
- If there are two concentrations contributing to rate, the rate order will be:
- What order rate is independent of concentration?
- That energy can never be created or destroyed but can only be converted from one form to another (energy of the universe is constant)
- Carbon dioxide, methane, nitrous oxide and fluoridated gases
- Positive enthalpy- a reaction absorbs more energy than it releases
- The amount of energy (heat) required for something
- Says entropy of the universe is always increasing (means all processes that occur in universe lead to wider distribution of energy in universe)
- Basically the law of conservation of energy (energy isn't created or destroyed just transferred and energy of the universe is constant)
- how many calories/joules is required to raise the temp of one gram of pure water by one degree celsius?
- does each substance have its own specific heat
- does every substance have a different heat of fusion or vaporization
- we cannot lose energy when transitioning between PE to KE
- is there an amount of heat associated with every chemical reaction
- what is the ΔH f° of and element in its standard state?
- how much energy does it take to raise 1g by a celsius
