Question

# In a zero order reaction for every $$10^o$$ rise of temperature, the rate is doubled. If the temperature is increased form $$10^o$$C to $$100^o$$C, the rate of reaction will become:

A
256 times
B
512 times
C
64 times
D
128 times

Solution

## The correct option is B $$512$$ timesFor rise in temperature, $$n=1$$Therefore rate $$=2^n=2^1=2$$When temperature is increased from $${10^ \circ }C$$ to $${100^ \circ }C$$    change in temperature $$= 100 - 10 = {90^ \circ }C$$ therefore $$n=9$$ therefore, rate $$=2^9=512$$ times.Chemistry
