If the reaction "P+Q→R+S' is deseribed as being of zero order with respect to P, it means that

Choose an answer

P is catalyst in this reaction

P molecules do not possess sufficient energy to react

The concentration of P does not change during the reaction

The rate of reaction is independent of the concentration of P

In dilatometric method is directly proportional to extent of reaction
