Question

In a zero order reaction.for every 10° rise of temperatue, the rate is doubled. If the temperature is increased from 10°C to 100°C, the rate of the reaction will become ______.

Options

• 256 times

• 512 times

• 64 times

• 128 times

Answer 1

In a zero order reaction.for every 10° rise of temperatue, the rate is doubled. If the temperature is increased from 10°C to 100°C, the rate of the reaction will become 512 times.

Explanation:

The reaction is zero order, so the rate is independent of concentration.

The rate doubles for every 10°C increase in temperature.

The temperature is increased from 10°C to 100°C, a total increase of

100°C − 10°C = 90°C

This corresponds to:

`90/10` = 9 steps of 10°C

Since the rate doubles each time:

Final rate = 2⁹

= 512
