Q79 / 180 · NEET 2013 (Karnataka) · Chemistry

A reaction is $50 \%$ complete in 2 hours and $75 \%$ complete in 4 hours. The order of reaction is:

Correct answer
A
1
B
2
C
3
D
0

Solution

A per the data given $$ t_{75 \%}=2 \times t_{30 \%} $$ $\therefore$ The order of the reaction is 1 .

Hence, the correct answer is option: 'A'.
