Rate of hydrolysis will have units g/s so that's how you get rate. The thing is 5 minutes long.

Would you not just plot the graph? Put temperature on the x axis and mass on the y axis
naaa mate that aint processed data

Rate of hydrolysis against temperature. It has to be rate due to biology reasons I can't remember.

Ohhh im soo dumb. I don't know why i do a-levels. Okay but how would i calculate the rate of hydrolysis? I assumed it was g s-1??

i swear down new spec makes me suicidal
5 minutes is 300 seconds. Divide each mass by 300 to get rate in g s-1.

would the first one be

48/300

because 5x60= 300 secs

my g is going to get an A* in biology and become a doctor.

Thank you xx

0.48 g of protein were hydrolysed in 300 seconds.

So, rate of hydrolysis 0.48/300 = 0.0016 g s-1

Yes. Although the unit below per is left blank so I'm not sure if it's necessary to have it per second and not per minute, for example. Guess you'll find out when you see the markscheme.

One offer. Liverpool. I need 3 A but don't have a clue how I did with biology and hoping I did well enough in chemistry. Just depends on grade boundaries now.

Good luck. My tip would be to stay composed in exams and don't stress too much.
