As we know, arrhenius equation, that is k is equal to ae t is to minus ea upon r2.
00:08
We need to calculate the ratio of the rate of reaction at 0 degree and 1 ,000 degrees.
00:13
Now first we'll see at 0 degrees celsius.
00:16
0 degree means temperature, it found to be 273 plus 0, that is equal to 273 kelvin.
00:24
And difference in activation energy, that is, ea is equal to 20, kilo jule per mole.
00:34
Now we need to convert it into joules so it found to be 20 ,000 joules per mole as we need to use this value only.
00:43
So here we can write k2 upon k2 dash upon k2 is equal to e minus ea upon as the a is the same frequency factor it cancel out minus ea upon rt.
01:01
Here we can write for e as a e dash, full divided, e minus ea upon rt.
01:09
So when we saw it, it found to be e raise 2, minus ea upon rt minus ea dash upon r2.
01:19
Okay, just we change the signs.
01:22
Then we can write it as a e raise 2.
01:24
Ea dash minus ea will take out 1 upon r t as a common with the minus sign okay that is a common one so we can write it like e r s 2 minus 1 upon r t a dash minus e a now what is this this is the difference in the activation energy and that is given that is here it is given as a difference okay this is the difference in activation in f so we just have to put this value and by putting that value it is found that e minus 1 upon rt and in place of that whole value we can write 20 ,000 then e raised to minus 1 upon rt now r is a gas constant so 8 .314 into temperature it is given as 273 that need to multiply by 20 ,000 now just by by by doing all this calculation, finally what you are getting, you are getting k2 dash upon k2, means the ratio of the rate of reaction, it found to be 1 .49 into 10 -2 minus 4...
