The commonly observed ratelaw of Benzoin condensation is rate = `K[ArCHO]^(x)[CN^(-)]^(y)` Then the value of x+y is

The value of (x/y)/(x/y+y/x) is

If cos x = k cos (x - 2y), then the value of tan (x -y).tan y is

If x+y=k is normal to y^(2)=4x ,then the value of k is

If 1/x+1/y=k and 1/x-1/y=k , then the value of y is:

If the line y=3x+k is tangent to the parabola y^2=4x then the value of K is

If the line y=sqrt(3)x+k touches the circle x^(2)+y^(2)=16, then find the value of k

The rate law for the reaction 2X +Y rarr Z is Rate = k[X][Y] The correct statement with regard to this relation is

The equation of tangent to the curve y=x+(4)/(x^2) , that is parallel to the x-axis is y = k. Then the value of k is?
