i need help with this question ..........
first , cant we find the value of -Ea/R just by using the table ???
i did -9.75--5.58 (missing value from table) / (3.41* 10^-3) - (3 * 10^-3)
and i got -10170.73
but the value in the markscheme is -10230
what is wrong with my method
if i plot a graph i will find out the gradient by y2-y1 / x2 - x1 anyways
i have one more q concerning the graph (nothing to do with this question tho)....
can we cut the x -axis, for eg. start from 3 * 10^-3 and and also cut the y-axis (becuase the always say that the line must cover half the graph) and still be able to find the y- intercept???????
bcz we neeed to find the a constant from the arrhenius equation, so will it be write to find the y axis interception and put it as the a constant if the axis' are cut ???
