In a first-order reaction, the instantaneous rate of reaction is given by the equation: \[ \text{Rate} = k [A] \] The slope of the graph at point C represents the rate constant \( k \), and thus, the instantaneous rate is directly related to the slope. The slope \( m \) of the graph represents the rate.
Given below are two statements:
Statement I: Viscosity of liquid decreases with an increase in temperature.
Statement II: The units of viscosity are kg m-1 s-2.
A hydrocarbon containing C and H has 92.3% C. When 39 g of hydrocarbon was completely burnt in O2, x moles of water and y moles of CO2 were formed. x moles of water is sufficient to liberate 0.75 moles of H2 with Na metal. What is the weight (in g) of oxygen consumed?
At 300 K, for the reaction A → P, the ∆Ssys is 5 J K-1 mol-1. What is the heat absorbed (in kJ mol-1) by the system?
