Answer 1

Heya

GIVEN REACTION IS

A ------> B

1) FOR IST ORDER REACTION RATE OF REACTION IS GIVEN BY

R -----> P

RATE = k [ R ]¹

2) FOR 2ND ORDER REACTION RATE OF REACTION IS GIVEN BY

2R ----> P

RATE = k [ R ]²

3) FOR THIRD ORDER REACTION RATE OF REACTION IS GIVEN BY

3R ----> P

RATE = k [ R ]³

=>

In this question rate of reaction is given by

Rate = k [ A ]

CONDITIONS GIVEN IS THE RATE OF REACTION BECOMES ( 27 TIMES ) WHEN WE INCREASE CONCENTRATION OF REACTANTS BY THRICE ( 3 TIMES).

THE ABOVE CONDITIONS SATISFIES ONLY IF

RATE = k [ A ]³

{ if u put A = 3A here u will get Rate is increased by 27 times }

Which is rate Equation for third order reaction.

So, Order of reaction is 3
