The rate law for a reaction between substance P \& Q is given by
Rate = k[P]^x [Q]^y
If concentration of P is doubled and concentration of Q is halved, the ratio of the new rate to the earlier rate of reaction will be : 

Half life of the zero order reaction is:

Which of the following is not an essential amino acid ?

Which statement is correct for solutions?

Read the passage carefully and answer the following questions
Aldehydes, carboxylic acids and ketones are widespread in the animal and plant kingdoms. They play a pivotal role in various biochemical processes of life. Their presence in nature adds fragrance and flavor. These compounds are widely used in food products, pharmaceuticals, paints, resins and other important product industries. These compounds are prepared by various laboratory methods, which mainly include oxidation, formylation, acylation and reduction. Due to the polar nature of the carbonyl group in aldehydes and ketones, they can exhibit different reactions like nucleophilic addition. They do exhibit redox and various condensation reactions which lead to the formation of various important compounds. On the other hand, the carboxylic acids are mainly prepared by oxidation and hydrolysis of different compounds. The carboxylic acid consists of a carbonyl group and the hydroxy group (attached to the carbonyl carbon atom). This makes it possible for the carboxylic acid to participate in various chemical reactions which involve cleavage of the C-OH bond and the O-H bond along with the reactions involving the complete - COOH group.
The IUPAC name of following compound is \(OHC-C_6H_4-CHO-p\)

In a typical test cross:

If \(y=\frac{1}{\sqrt[3]{1-x^3}}\), then \(\frac{d y}{d x}\) is equal to :

If \(f(x)=\left|\begin{array}{ccc}0 & x-1 & x-2 \\ x+1 & 0 & x-3 \\ x+2 & x+3 & 0\end{array}\right|\), then the value of f(0) is equal to:
