Question

The reaction L to M is started with 10g/L.after 30 and 90 min ,5g and 1.25g/L are left respectively .the order of reaction?

Answer 1

Hey mate,

# Answer- First order reaction

# Explaination-

Reaction occurs as follows,

L ---> M

Initially L was 10 gram

In 30 minutes it decreases to 5 gram i.e.50%

In 60 minutes it decreases to 2.5 gram i.e.25%

In 90 minutes it decreases to 1.25 gram i.e.12.5%

We observe uniform decrease in reactant here, Hence this is a first order reaction.

Hope this is useful...

Answer 2

Answer:

1order

Explanation:

since there is decreased y 50%first time and then uniform decreased is scene therefore it is 1st order
