Acetylene, c2h2, can be converted to ethane, c2h6, by a process known as hydrogenation. the reaction is c2h2(g)+2h2(g)? c2h6(g)given the following data, what is the value of kp for this reaction? substance ? g? f(kj/mol)c2h2(g) 209.2h2(g) 0c2h6(g) ? 32.89in part a, we saw that ? g? =? 242.1 kj for the hydrogenation of acetylene under standard conditions (all pressures equal to 1 atm and the common reference temperature 298 k ). in part b, you will determine the ? g for the reaction under a given set of nonstandard conditionsat 25? c the reaction from part a has a composition as shown in the table below. substance pressure(atm)c2h2(g) 3.85h2(g) 4.45c2h6(g) 1.25

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
