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
