i baru je abis class BEL (english) tdi...
xde pe2 pn yg kiterg blaja time class BEL tdi...
sbb lcturr de meeting...
dtg tdi pn tuk sign attendance je la..
tgh ari tdi..
i de lab chemistry (chem)
kn i dh jnji nk citer psal sbjk chem plak??
s0o..nk xnk..kene la i tunai kn jnji i tue...
lab kali nie kiterg stdy psal KINETIC
nk taw fact0r yg affect rate of reacti0n..
sng je bt experimen nie..
cam men msak2 taw...
de 2 experiment..
first...
cmpr KI ngn Na2S2O3 ngn Na2S2O8 ngn H2O with varies v0lume..
tp t0tal v0lume kene fixed...50mL..
sbb expriment 1 nie nk tgk rate of reacti0n bila c0ncentrati0n of s0lution tue kite varies-kan..
nk taw sape yg cpt react...
yg pekat ke??yg cair??
tp dlm experiment nie...
sure la yg pekat kn..
tuk experiment 2 plak..
nk tgk temperature plak..
same cam tdi gak...
tp sebelum campur kn Na2S2O8 ..kita kene ltak mixture tue kt dlm beaker yg de ais..tuk turun kn suhu s0lution tue..
gr0up i bt temperature dier de yg 5, 10 and 20 degree celcius...
lpas s0lution dh reach temp. yg kiterg nk tue..
msk la Na2S2O8 kt dlm s0lution yg kiterg dh sjuk kn tdi..
then amek la mse tuk s0lution tue bertukar c0lor...
mkin rendah suhu...mkin lmbt la rate of reacti0n dier...
sbb m0lecule sume dh xactive dh...
sbb energy dierg dh l0w bila sjuk...
nie i de selit skit pic2 tuk u all santap...
langkah2 yg diambil utk menjaya kn experiment
datasheet yg perlu diisi...
