Expert Answer
Let the reaction be,
 
X(g) → P
 
Rate of reaction = k[X]n    ..........(1)
 
When volume id doubled, concentration becomes half.
 
Rate of reaction also become half.
 
Rate over 2 equals straight k space open parentheses fraction numerator left square bracket straight X right square bracket over denominator 2 end fraction close parentheses to the power of straight n space space........ open parentheses 2 close parentheses

From space eq space open parentheses 1 close parentheses space and space open parentheses 2 close parentheses

Rate cross times 2 over Rate equals space straight k left square bracket straight X right square bracket straight n cross times straight k open parentheses fraction numerator 2 over denominator left square bracket straight X right square bracket end fraction close parentheses to the power of straight n

space space space space space space space space space space space space space space space space 2 space equals space open parentheses 2 close parentheses to the power of straight n

space space space space space space space space space space space space space space space space straight n space equals space 1
It is first order reaction.
