how we write the relationship between rate of reaction with the temperature?

Can we use : Rate of reaction is directly proportional to the temperature.
I'm confused with this because my school chemistry teacher who is experienced in marking Paper 3
told me that if I'm using
Rate of reaction is directly proportional to the temperature.
as my answer, i'll only get two marks out of three!
she told me that the correct/perfect answer should be "when the temperature increase, the rate of reaction increase"

So, which one is the correct answer or any others solving tips?

[Jong Kah Yin]

Hi,
Your school chemistry teacher is correct- it maybe proportional but not necessarily directly proportional.
Answer such as "when the temperature increase, the rate of reaction increase" or "the higher the temperature, the higher the rate of reaction" can be accepted.

Thanks a lot>

when we want to write relationship,  we need to write manipulated variable first, then we write responding variable. How if we write in reverse way ?

Ya, i came across students that answer these kind of questions in the ways as you said, Cgu Berdie. May be we can seek advices from Mr. Lim or Mr. Jong, or even other experienced teachers as well.

i thi k you need to seek advice from language teacher.
 For example, relationship between the rate of reaction and the temperature of reactant. Most of the time we write " The higher the temperature, the higher the rate of reaction occured." If you try to write it reversely, " The higher the rate of reaction, the higher the temeprature" If you write like this, it show some other meaning instead of temperature affect rate of reaction.

Just my opinion.
