Question

the temperature coefficient of a reaction is 2 and the rate of the reaction at 25degree celcius is 3 mol lit min calculate the rate at 75 degree celcius

Answer 1

Answer:

Explanation:

According to Arrhenius , for every 10°c rise in temperature, the rate of reaction is doubled.

Rise in temperature = 75°c-25°c=50°c

That is 5 × 10°c

The increase in rate of the reaction is 2 power 5 = 32 times ...

The rate of reaction at 75°c is = 3 × 32 = 94 molL~min~

Answer 2

rate at 75 degree celcius  will be  94 molL/min.

Explanation:

The rate of reaction doubles with every 10°C increase in temperature, according to Arrhenius.

Temperature rise: 75°C minus 25°C equals 50°C

It is 5 x 10 °C.

The increase in rate of reaction will be 2^n(2 to the power n)

so,

The reaction's rate has increased by 2 power 5 times that is equals to  32 times.

At 75 °C, the reaction occurs at a rate of = 3 x32 = 94 molL/min.
